fix(print): Print Anyway per printer, variant plate, nozzle per plate, sliced .3mf drop

Print Anyway now only covers the printers whose warning it answered; an
untouched variant plate dropdown sends the plate it shows; the nozzle per
filament comes from the chosen plate; and a sliced 3MF named without
.gcode can be dropped on a printer card or uploaded for print.

CHANGELOG.md

@@ -163,6 +163,11 @@ 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
+- **Print dialog fixes** —
+  - **Print Anyway** in a print to several printers now only waves through the printers whose filament warning it answered. Before, it went onto every selected printer, so one that was never checked also skipped the scheduler's filament checks.
+  - A job with printer alternatives whose plate dropdown was left untouched showed **Plate 1** but was queued with no plate, so it asked for every plate's filaments and the whole file's print time and could find no printer.
+  - On H2D and H2C, the nozzle shown for each filament now comes from the chosen plate, not from all plates of the file, which could match trays on the wrong nozzle.
+  - A sliced 3MF named without `.gcode` (a plate exported from Bambu Studio) can now be dropped on a printer card or picked in **Upload for Print**. An unsliced 3MF is refused with a message saying so.
 - **Orders and groupings show as finished however their last job ended** — An order or grouping was only re-checked when a print completed, an item was deleted or one was edited. A grouping whose last job was cancelled or stopped, or whose jobs were cancelled because their library file was deleted, an order whose last run was closed by the stuck-print cleanup, and one whose last open job failed before it reached the printer or was deleted, stayed **active** until the next restart. They are now re-checked on every way a job ends.
 - **A job cancelled while it is being sent stays cancelled** — Cancelling a queued job during its upload (the edit dialog even asks you to cancel a job that is being sent) was overwritten when the upload then failed: the job turned into a failure, a failure notification went out, and the next job that needs the previous print to have succeeded was skipped. A failure is now only recorded for a job that is still waiting or printing, and the upload toast of a cancelled job closes instead of spinning. Likewise, a job stopped just as its printer turned busy is no longer put back in the queue, and a stopped job whose nozzle rack pick no longer fit no longer leaves its file on the printer.
 - **"Only if the previous print succeeded" looks at the right printer** — For a job queued for any printer of a model, the check ran before a printer was chosen, against jobs with no printer, so it nearly always let the job go, even onto a printer whose last print had failed; when it did trigger, the job was skipped for good. It now checks the printer it is about to use, passes over one whose last print failed and takes another of the model, and waits if every free one failed last. The queue then shows a **Resume after failure** banner for that model, which clears the gate on its printers, and the "job waiting" notification also goes out when a job that waited for a busy printer comes to wait on such a failure. On PostgreSQL, a job cancelled without an end time (cancelling an order, a pipeline or a kept order run) also counted as the latest print and hid a real failure before it; such cancels now record their end time, and the check no longer ranks a missing one first.
