feat: Add quick wins batch (#42, #43, #25, #35, #20, #36, #39)

- #42: Allow spools heavier than theoretical max (remove weight clamps)
- #43: Show filament custom fields on spool detail page
- #25: Sort spools by custom fields and remaining weight
- #35: Global search box for spool list
- #20: Gallery view for spools (color grid with progress bars)
- #36: Spool-level color override with ColorPicker
- #39: Cost analytics endpoint, total spent & avg cost/kg stats
- Fix: Filament select refresh after inline creation
- Fix: Parse temperatures from filament comments
