- Created shared color utility (frontend/src/utils/colors.ts):

- Moved BAMBU_HEX_COLORS mapping and getColorName()/hexToColorName() functions to a shared location
  - Exported functions for use across components

- Updated modals to use shared colors:
  - ReprintModal.tsx - removed ~100 lines of duplicate color code, now imports from utils/colors
  - AddToQueueModal.tsx - same cleanup
  - EditQueueItemModal.tsx - same cleanup

- Added AMS mapping to EditQueueItemModal:
  - Added state for showFilamentMapping, isRefreshing, manualMappings
  - Added queries for filament requirements and printer status
  - Added loadedFilaments, filamentComparison, amsMapping memos
  - Added collapsible filament mapping UI section (same as other modals)
  - Initializes manualMappings from existing item.ams_mapping
  - Submits ams_mapping when saving changes

- Backend changes:
  - Added ams_mapping field to PrintQueueItemUpdate schema
  - Updated update_queue_item route to serialize ams_mapping to JSON

- Frontend API client:
  - Added ams_mapping to PrintQueueItemUpdate interface

- Changed "Print" to "Reprint" on archive card button (ArchivesPage.tsx:690)

- Bumped service worker to v22
