Add manual AMS slot selection for prints (#76)

- ReprintModal: Dropdown to override auto-matched AMS slots
- AddToQueueModal: Collapsible filament mapping section
- Backend: Store ams_mapping in print queue, apply when print starts
- Color names in dropdowns (decoded from Bambu codes or derived from hex)
- Blue ring indicator for manually selected vs auto-matched slots
- Status indicators: green (match), yellow (type only), orange (not found)

Closes #76
