PR #79 – Update

This pull request introduces a versioned REST API, improves filament/print UI output, and hardens logging around sensitive device identifiers. :contentReference[oaicite:0]{index=0}

✨ New Features

• Versioned REST API: API routes are now served under a versioned prefix (/api/v1) to enable future evolution without breaking clients. :contentReference[oaicite:1]{index=1}
• New REST endpoints for printer + AMS + spools
  • List printers: GET /api/v1/printers
  • Get AMS slots/trays for a printer: GET /api/v1/printers/<printer_id>/ams
  • List spools: GET /api/v1/spools
  • Assign a spool to a tray: POST /api/v1/printers/<printer_id>/ams/<tray_index>/assign
  • Unassign a tray: POST /api/v1/printers/<printer_id>/ams/<tray_index>/unassign

🛠 Improvements

• Print history / filament UI: show used filament length in mm (incl. slicer metadata length where present), with improved tooltips for better readability.
• Large number formatting for mm values (thousands separators) to make long prints easier to scan.
• API spool serialization extended with weight_g (derived from spool initial weight or filament weight) for richer client-side display/logic.
• Color mismatch signal quality: tray/spool color mismatch evaluation now includes a computed color distance (only for single-color spools) and carries mismatch details through the tray serialization.

🐛 Bugfixes

• Filament mismatch logging correctness: fixes cases where mismatches were not logged or were logged incorrectly, improves update behavior when tray IDs collide/duplicate, and ensures the active spool is handled consistently.
• Mismatch log location cleanup: mismatch log moved into the logs/ folder (e.g., logs/filament_mismatch.json) to keep state/artifacts in the expected place.
• fixed spool assignment issue

🔒 Security / Privacy

• Mask printer serial numbers in mqtt.log: MQTT payload logging now redacts serial/SN-like values before writing to disk.
