fix(archives): let Items Printed go to 0 for a ruined plate (issue #3051)

A jam can destroy everything on the plate while the printer still reports the
job as a success, so the honest count of usable parts is zero. The edit dialog
floored the field at one, and a project's completed-items count sums that
column, so there was no way to record that a job produced nothing.

The floor was in the dialog only; the API stored whatever it was given, which
also meant a negative count was accepted and would have subtracted from the
project totals. The column is now bounded at zero instead.

Filament Trends counted prints as `quantity || 1`, which would have read a
deliberate 0 as "unset" and charged the ruined plate as one print while the
project page counted none.

 - **Every FTP session Bambuddy opens now records how it closed (#3009, reported by @grengojbo)** — the report traced a print completion that opened two FTP connections to the printer, deleted one file and then, as far as the log showed, did nothing else until the printer was powered off 21 minutes later, and concluded the connections were being left open. They were not: the post-print SD-card cleanup opens one connection per candidate filename and closes each in a `finally`, which a run against a real FTPS server confirms at the server end for both the delete and the 550 not-here case. The trouble is that nothing in the log could have said so. Neither the clean close nor the hard socket drop logged anything at any level, so a session closed properly and a socket genuinely abandoned produced the same output — none — and the only way to tell them apart was to read the source. Both now log one DEBUG line naming the printer, whether QUIT was acknowledged or the socket had to be dropped without it, why, and how long the session was held. Every connect in a debug log is now paired with a close, so the next person suspecting a leaked FTP connection can settle it from a support bundle rather than by inference. Nothing about the connection handling itself changed, and at default log level nothing new is printed. This does not explain the SD-card read/write error in that report or in #645; it only removes one theory from the list by making it checkable.
 
 ### Fixed
+- **Items Printed could not be set to 0 after a total plate failure (#3051, reported by @tdavis75)** — a jam ruined everything on the plate while the printer reported the job a success, so the honest count of usable parts was zero; the field refused to go below one. The manual quantity override is what the documentation points at for exactly this correction, and a project's completed-items count sums that column, so there was no way to tell a project that a job produced nothing. The floor was in the edit dialog alone — the API had always stored whatever it was given, which also meant a negative count was accepted and would have subtracted from the project totals. Zero is now typeable and the column is bounded at zero, and the Filament Trends widget counts a zeroed archive as no prints rather than silently reading the 0 as "unset" and charging one.
+- **Bulk edit could not turn G-code injection on or off (#3058)** — every other per-item print option in the queue can be changed for a whole selection at once, but **Inject G-code** was only ever settable one item at a time, in the item's own edit dialog. The bulk dialog simply had no control for it, which on a queue of a few dozen jobs meant opening every single one to arm the start and end snippets an auto-print system needs — the thing bulk edit exists to avoid. It is now a tri-state next to **Auto power off after print**, unchanged by default like the rest, and it appears only once a G-code snippet has actually been saved for some printer model, matching the checkbox in the print dialog. Nothing changed on the server: the bulk endpoint has always accepted the field, so this was a missing control rather than a missing capability.
 - **AMS Filament Backup switched itself off with every print started from the queue (#3040, reported by @frnzzle)** — it never actually did: the printer had auto-refill on the whole time, and Bambuddy was reading its own request back as telemetry. Every `project_file` Bambuddy sent carried `"cfg": "0"`, a field Bambu Studio has never sent and the firmware ignores, but the printer echoes a command's fields back in its acknowledgement — and `cfg` is the device-config bitmask whose bit 18 is auto-refill. The acknowledgement was ingested as though it were a status frame, so 25 ms after every dispatch the badge flipped to off. On a P2S, H2C or X2D it flickered back a second later, because those repeat `cfg` in their periodic status; the P1S, A1, A1 Mini and A2L send it only in a full status dump, which arrives on connect and on Force Refresh and otherwise not at all, so there the wrong value stood until someone toggled it by hand. That mattered beyond the badge: the "prefer lowest remaining" sort is deliberately skipped while the printer reports backup off, since without a second spool to fall back on, feeding a print from the emptiest one risks running dry mid-job — which is why near-empty spools were being left untouched, the symptom that opened the report. On the A1 family it was worse still: they report no `cfg` at all, and the state is meant to stay "unknown" so that behaviour is left exactly as it was before the feature existed; the echo turned that into a definite "off" on the first queue print. Command acknowledgements are no longer read as status — for the backup bit or for the per-job timelapse flag they also echo — and the `cfg` field is gone from the print command, which is not a place to be writing printer settings from.
 - **K values missing on a second AMS, and its slots unconfigurable (#3044, reported by @Zib-Astian)** — an X2D with two AMS 2 Pro, one per hotend, showed K on every slot of the first and nothing on any slot of the second. Configure Slot was worse than blank there: the picker offered no matching profile, the slot read as though it had none bound, and choosing one changed nothing visible. Both came from the same rule. A calibration index can mean two different profiles on a dual-nozzle printer — on the maintainer's H2C, index 16 is the left hotend's black PLA at K=0.018 and 15 is the right's at K=0.020 — so Bambuddy resolves it against the slot's own hotend and shows nothing rather than the wrong number. But a printer does not always file one profile per hotend. This one files one per filament, so the second AMS's slots point at the same entries as the first, all tagged with a single extruder, and requiring a match found nothing at all. The hotend now has to actually appear in the table the printer sent before it is used to narrow anything; where it does not, the index stands on its own, which is what BambuStudio does for the same card. Printers that do file per hotend are unaffected — the wrong-nozzle number still cannot be shown, and the other hotend's profiles stay under **Other K profiles**. Also fixed alongside it: on a dual-nozzle printer the K-profile dropdown named the hotend twice on every matching option and three times on every other one.
 - **The Timeline ignored Shortest Job First (#3043)** — turning SJF on reordered the pending list and the scheduler itself, but the Timeline tab kept drawing the queue in its pre-SJF order, indefinitely. It chained each swimlane's bars by queue position alone and was never told the setting existed, so the one view whose entire job is to say *when* each print will run was the one view answering for an order the scheduler had no intention of using. Bars now chain in the scheduler's own order — jumped items first, then shortest print time, then position — and the starvation guard is visible there too, so a long print that has finally come up shows as such instead of staying buried. All three surfaces that claim to show queue order (the pending list, the "if started now" ETA, and the Timeline) now share one comparator rather than three hand-copied ones. Along the way the pending list stopped folding a model name down to its first letter when grouping lanes, which had been interleaving *Any X1C* with *Any X2D* (and *Any P1S* with *Any P1P*) into a single run of rows.
