Add HMS error notifications with translations and plate detection fixes

New Features:
- HMS error notifications with human-readable messages (853 error codes)
- Plate not empty notification category (separate toggle in settings)
- Module-friendly names: Print/Task, AMS/Filament, Nozzle/Extruder, etc.
- Backup/restore now includes plate calibration reference images

Fixes:
- Plate calibration images now persist after restart in Docker
- Telegram notifications no longer fail on error codes with underscores
- Plate detection combo button: main toggles detection, chevron opens modal

Tests:
- Added HMS error code tests (10 tests)
- Implemented Dashboard, FileManagerModal, UploadModal tests (previously skipped)
- Added notification service tests for HMS errors and plate detection
- Fixed AuthContext unmount memory leak in tests

 ### New Features
+- **HMS Error Notifications** - Get notified when printer errors occur (Issue #84):
+  - Automatic notifications for HMS errors (AMS issues, nozzle problems, etc.)
+  - Human-readable error messages (853 error codes translated)
+  - Friendly error type names (Print/Task, AMS/Filament, Nozzle/Extruder, Motion Controller, Chamber)
+  - Deduplication prevents spam from repeated error messages
+  - Publishes to MQTT relay for home automation integrations
+  - New "Printer Error" toggle in notification provider settings
+- **Plate Not Empty Notification** - Dedicated notification category for build plate detection:
+  - New toggle in notification provider settings (enabled by default)
+  - Sends immediately (bypasses quiet hours and digest mode)
+  - Separate from general printer errors for granular control
 - **USB Camera Support** - Connect USB webcams directly to your Bambuddy host:
   - New "USB Camera (V4L2)" option in external camera settings
   - Auto-detection of available USB cameras via V4L2

 ### Fixes
+- **Plate Calibration Persistence** - Fixed plate detection reference images not persisting after restart in Docker deployments
+- **Telegram Notification Parsing** - Fixed Telegram markdown parsing errors when messages contain underscores (e.g., error codes)
 - **Settings API PATCH Method** - Added PATCH support to `/api/settings` for Home Assistant rest_command compatibility (Issue #152)
 - **P2S Empty Archive Tiles** - Fixed FTP file search for printers without SD card (Issue #146):
   - Added root folder `/` to search paths when looking for 3MF files
