Fill in missing generic filament IDs and fix support-filament setting IDs (#3273)

CHANGELOG.md

@@ -161,6 +161,8 @@ All notable changes to Bambuddy will be documented in this file.
 - **The frontend build no longer warns about `path` and `crypto` being externalized for the STEP previewer (#2976)** — `occt-import-js`, the Emscripten build behind STEP previews, requires both modules, but only inside its `ENVIRONMENT_IS_NODE` branches; in the browser it loads its `.wasm` from the URL the preview worker passes and draws randomness from `crypto.getRandomValues`. Vite still externalized both and printed two warnings on every build. `vite.config.ts` now drops exactly those two warnings for that one package through `build.rolldownOptions.onLog`, so an externalization anywhere else, or of any other module, still shows.
 
 ### Fixed
+- **A PP spool without a slicer preset was sent to the AMS slot with no filament ID (#3273, reported by @sgiffhorn)** — When a spool has no preset of its own, Bambuddy fills in Bambu's generic preset for its material. The table used for spool assignment had no entry for PP, PE, PCTG, PLA Silk or PLA High Speed, so those slots got an empty filament ID, while **Configure AMS Slot** used a separate, longer table. The backend now has one table with all five, matching the one the frontend already used. A slot already set to Generic PLA Silk or PLA High Speed still keeps it when a PLA spool without a preset is assigned, as before.
+  - **PVA, HIPS and Bambu support filaments got the wrong setting ID:** their filament IDs start with `GFS` (Generic PVA is `GFS99`), which Bambuddy took for a setting ID. It sent `GFS99` instead of `GFSS99` and read it back as `GF99`.
 - **Every start filled the PostgreSQL log with about 320 errors** — On PostgreSQL, the startup migrations re-ran every column, index and constraint they had already added, and the database logged each of those as an `ERROR` with its statement, about 640 lines per start, before Bambuddy quietly skipped it. Nothing was wrong, but the noise buried real errors and alarmed anyone reading the log, on the appliance as much as on Docker with PostgreSQL. On PostgreSQL these statements now ask the database to skip what is already there (`IF NOT EXISTS`, or a check of the catalog for constraints and renames), so a normal start logs no errors. Columns, renames and constraints that are actually missing are still added, and SQLite is unchanged. PostgreSQL 13 or newer is required, and the wiki now says so: Bambuddy has never started on PostgreSQL 12 or older, whose startup migrations fail on a column type those versions reject.
 - **A large timelapse could not be attached when it took more than 5 minutes to download (#3272, reported by @dovmesiz)** — Scanning for a timelapse, picking one by hand and the automatic attach after a print all gave the download a flat 300 seconds. A 75 MB video that took 358 seconds over a healthy P1S link failed with "Failed to download timelapse", and each retry started the file again from scratch. The time allowed now follows the file's size, so a slow transfer completes; a link that stops sending still fails after the FTP timeout as before.
 - **A printing queue job showed the slot AMS Filament Backup had switched away from as empty** — When a spool ran out mid-print and the printer carried on from the backup spool, the job's card in the queue still named the original slot, now marked **Empty**, as if the print had a problem. The card now shows the backup spool the printer is using. It follows the printer's own record of the trays the print has drawn from, including a backup that ran out in turn. A switch between two slots the job uses is a normal colour change and is not taken for a backup. Queued jobs still warn about an empty slot as before.
