fix(archives): failed print card says its cost is one full print (issue #3318)

- After a failed or cancelled print, the archive card showed the whole
  file's cost and grams with no hint, as if that run cost that much.
  The archive keeps one full print's figures on purpose (COST-3); the
  card now says so in a tooltip on the cost and grams for failed,
  aborted, cancelled and stopped archives, pointing to the Print Log
  for what the run used. New key in all 15 locales.
- archive_cost_estimate.py docstring no longer claims a failed print
  ends up cheaper on the archive.
- ArchivesCostEstimate test covers a failed and a cancelled card and
  finds cards by value rather than order.

 - **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 failed or cancelled print's card says its cost is for one full print (#3318, reported by @ojimpo)** — After a print failed or was cancelled, the archive card showed the cost and grams of the whole file with no hint, as if that were what the run cost. The archive keeps one full print's figures on purpose (reprints are estimated and billed from them); the cost and grams now carry a tooltip saying so, pointing to the archive's Print Log for what the run used. With Spoolman, that run's cost is priced from the spools it was charged to.
 - **A print that fails or is cancelled early is charged only for the filament it used (#3317, reported by @ojimpo)** — Two errors added up to a failed print being charged to Spoolman as if it had finished, sometimes for more than the finished print would have used.
   - **The previous print's layer:** right after a print starts, the printer can send one update that still carries the layer the previous print ended on (seen on an H2S: layer 357 of 357 at 0 %). Bambuddy took it as this print's last layer, so a print that failed before its first layer was charged up to layer 357. That value is now ignored until the new print reports a layer of its own. It also no longer counts as a layer change, so it no longer adds a layer-timelapse frame at print start.
   - **Retractions:** partial usage is worked out from the extrusion in the file's G-code, which counted each un-retract but never the retract before it. Every retraction added to the total, putting partial usage up to 1.7x above the slicer's weight. Retractions are now subtracted. The split between spools after an AMS switch to a backup spool mid-print uses the same figures.
