fix: follow-up fixes for logo sync and filament spool_count

[akira69]

Summary

Follow-up PR on top of merged fork work to harden logo sync behavior, spool-count handling, and UI consistency.

Fixes Included

• Preserve existing vendor logos on sync failure by staging downloaded content and only swapping after successful validation/write.
• Support arbitrary Git refs (branch/tag/SHA) for vendor logo tarball downloads instead of forcing refs/heads/<branch>.
• Use getAPIURL() for vendor logo sync calls in vendor edit so base-path deployments work.
• Fix filament list spool_count sorting/filtering 500s and optimize the spool_count query path.
• Add migration index on spool.filament_id with column-based duplicate detection to avoid redundant FK indexes.
• Co-extruded preview + table/filter UX follow-up fixes included from this branch iteration.

Validation

• PYTHONPYCACHEPREFIX=/tmp/pycache python3 -m py_compile spoolman/vendor_logos.py
• PYTHONPYCACHEPREFIX=/tmp/pycache python3 -m py_compile migrations/versions/2026_02_20_1605-b5f9c2e31a1b_add_index_on_spool_filament_id.py
• docker run --rm -v "$PWD:/app" -w /app/client -e VITE_APIURL=/api/v1 -e NPM_CONFIG_CACHE=/tmp/.npm -e XDG_CONFIG_HOME=/tmp/.config -e HOME=/tmp node:20 /bin/bash -lc "npm ci && npm run build"

Manual Checks

• Vendor edit: GitHub logo sync works under base-path deployments.
• Vendor logo sync safety: failed/aborted sync does not delete existing runtime logos.
• Filament/spool list: spool_count sorting/filtering works without 500s.
• UI checks: clear-filters state, column controls, and color preview behavior.

Upstream References

This work builds on the filament label flow introduced in PR Donkie#846 and extends it with manufacturer-logo support and related UX improvements.

Addresses / Advances Existing Upstream Requests

• Ability to print QR-codes for Filament aswell as Spool Donkie/Spoolman#824 — Ability to print QR-codes for Filament as well as Spool

  • Extended and refined filament print/export label workflows.

• QR code for sample tags Donkie/Spoolman#662 (partial) — QR code for sample tags

  • Filament label generation/export with QR support is included; this does not implement a full sample-tag feature set.

• Niimbot Label Printer Integration? Donkie/Spoolman#320 (partial) — Niimbot Label Printer Integration?

  • Adds/expands AML/PNG export paths and ZIP-based per-label export workflows compatible with external label tooling.

Relation to Earlier PR

• Follow-up to PR feat(printing): filament label printing foundation Donkie/Spoolman#846 (filament print/export + AML/PNG groundwork).
• This PR adds manufacturer logo capabilities and UI/flow improvements on top of that baseline.
• Any logo-sync robustness/base-path/ref handling fixes are fixes to this new feature set (not pre-existing upstream main bugs).

Follow-up QA note:

• Updated table column double-click auto-fit logic so it measures intrinsic cell content and only expands when content is actually overflowing (prevents the prior "always grows a bit" behavior).
• Rebuilt and redeployed to LXC for runtime validation; service health is OK after deploy.

I also cleaned up the PR description text so the fix bullets show the correct code references (for example, getAPIURL() and refs/heads/<branch> details).

[akira69]

Branch cleanup complete:

• Force-updated feat/manufacturer-logo-labels to the cleaned commit series from feat/manufacturer-logo-labels-clean.
• Folded the latest auto-fit bugfix into the existing table commit (no extra standalone bugfix commit added).
• PR now includes latest commit bfa9681 (feat(tables): pin Actions column and add double-click auto-fit for resized columns).

Also updated PR description with an explicit upstream-linkage section so it is clear which changes map to upstream requests and which are UX hardening follow-ups.
