Queue VP target can be cleared; script adds the slicer certificate

- Queue mode: the target picker's first entry reads "Any available
  <model>" and clears the target (null), with a hint saying where jobs
  go; the API takes an explicit null as "clear"; proxy mode still needs
  a printer
- Settings > Virtual Printer: download a script for Windows (.cmd) or
  Linux / macOS (.sh) with this instance's CA written in; it adds the CA
  to Bambu Studio's and OrcaSlicer's printer.cer, keeps a backup, does
  nothing when present, and drops an earlier issue of the same CA
- Windows: elevates itself and installs a SYSTEM task (startup, logon,
  hourly) that re-adds the CA after slicer updates; it only touches
  slicers under Program Files and skips paths with links
- Tests run both scripts against a fake slicer tree (pwsh when present)

 ## [1.3.1b1] - Unreleased
 
 ### Added
+- **A script adds the virtual printer certificate to the slicers** — Bambu Studio and OrcaSlicer only connect to a virtual printer whose certificate is in their printer.cer file, and every slicer update or reinstall puts the original file back, so the certificate had to be added by hand again. The **Slicer certificate** card under Settings > Virtual Printer now downloads a script for **Windows** or **Linux / macOS** with this Bambuddy's certificate already in it. It finds Bambu Studio and OrcaSlicer, adds the certificate, and keeps the original file next to it. It changes nothing where the certificate is already there, and it removes an older certificate of the same Bambuddy, which would otherwise stop the slicer from connecting. On Windows it is a double-click: it asks for administrator rights, and it installs a task that adds the certificate again at every start, at every sign-in and once an hour, so a slicer update no longer breaks the connection (`/uninstall` removes the task). On Linux and macOS it runs with bash, and is run again after a slicer update. Wiki updated.
 - **WLED lights show the printer's status (#1528, requested and contributed by @d3nn3s08 in #3124)** — A WLED controller can now show what each printer is doing. Under **Settings > WLED**, pick a printer, enter its WLED address and assign one of the presets saved in WLED to each state: Idle, Preparing, Printing, Paused, Finished, Failed / Error, Awaiting plate clear, Filament problem, HMS error and Offline. Colours, effects and segments stay in WLED; Bambuddy only switches presets. A state without a preset falls back to the next one that has one (a filament runout without its own preset shows Paused). **Awaiting plate clear** applies only while the queue's **Require plate clear** setting holds the printer, and **Filament problem** only when the printer paused because the filament ran out. An optional timeout switches Finished back to Idle. The page can test the connection, load the presets from WLED and try each preset on the strip. If WLED is unreachable, Bambuddy retries every 30 seconds and logs the outage once. Several printers can share one controller when each preset is saved with "Checked segments only". The tab needs the `printers:update` permission.
 - **Cam Wall tiles show temperatures and finish time, and can pause, stop and switch the light (#3479, sponsor vote Q4 2026)** — With the **Full** status overlay, every connected tile shows its nozzle (both on a dual-nozzle printer), bed and chamber temperatures, and a printing tile adds its finish time beside the time left. Hovering over a tile shows **Pause/Resume** and **Stop**, with the same confirmations as the printer card, and a **chamber light** switch; **Tile controls: Always** in the wall settings keeps them on screen, and a touch screen always shows them. The controls need the `printers:control` permission; a user without it, an offline printer and a Cam Wall token (kiosk) wall get none.
 
 ### Changed
+- **A queue virtual printer shows where its jobs go, and its target can be cleared** — In Print Queue mode a virtual printer without a target printer sends each job to the next free printer of its model, but the card's target list only said "Select a printer...", and once a printer was picked there was no way back. The first entry now reads **Any available [model]** and switches the virtual printer back to that, and a line under the list says where the jobs go. The access code stays the same, so the slicer stays bound. In the other server modes the entry reads **None**; proxy mode still needs a printer. Wiki updated.
 - **Profile defaults is compact and has Apply all** — Settings → Filament → Profile defaults showed every default as a large box with all its presets and K profiles, so a few products already filled the page. Each default is now one line (product, colour, slicer preset, and how many printer presets and K profiles it has), sorted by product, with a search box; click a line to see its presets and K profiles. The list scrolls on its own. **Apply all** applies every default to the spools in stock in one go, and like Apply to existing spools it only fills in what a spool doesn't have yet. Wiki updated.
 - **Slicer sidecars on Bambu Studio 02.09.01.70 and OrcaSlicer 2.5.0 (#3442)** — The Bambu Studio sidecar now ships the H3C printer presets (0.2, 0.4, 0.6 and 0.8 mm nozzle). OrcaSlicer has no H3C presets yet. OrcaSlicer 2.5.0 ships its bundled presets in a new packed format, so the sidecar image now fetches the same release's presets as JSON for its preset handling. Slicing with a printer preset saved under a name of its own keeps working on 2.5.0; the sliced file then names the Bambu preset it was saved from as its printer preset. Sidecar images built for older slicer versions work as before.
 - **"Any model" jobs go to the printer with the fewest print hours (#3480, sponsor vote Q4 2026)** — When several printers of a model can take a job, the queue used to pick the first one in its list, so on a farm the same printer got most of the work. It now picks the one with the fewest print hours (the Maintenance counter, including baseline hours entered there), so jobs and wear spread across the farm. Preferred colours still come first, and the queue powers on the least used printer too when it has to switch one on with an Auto Power On plug.
