- Added query to fetch library file details in PrintModal
- Updated backend FileResponse schema to include metadata fields (print_name, print_time_seconds, filament_used_grams, sliced_for_model)
- Updated backend get_file endpoint to extract and return metadata fields
- Updated frontend LibraryFile interface to include metadata fields
- Now slicedForModel is properly extracted from both archives and library files

Addresses reports of files being automatically reprinted hours after
the original print completed. The root cause was a race condition where
the queue item status was updated to "printing" AFTER the print command
was sent, allowing stuck "pending" items to be re-triggered on restart.
Changes:
- Set status to "printing" BEFORE sending print command to prevent
re-triggering if backend crashes after print starts
- Add 24-hour expiration for stale pending queue items
- Add duplicate prevention: skip archives completed within last 4 hours
Trade-off: If backend crashes after status update but before print
command, item will be stuck in "printing" without actually printing.
This is safer than accidentally reprinting and wasting filament.
The ams_mapping2 format was incorrectly using the tray_id (254/255) as
the slot_id for external spools. The printer expects slot_id to be the
actual slot index (0 for main nozzle, 1 for deputy nozzle), not the
tray_id value.
Before: {"ams_id": 255, "slot_id": 254} <- invalid slot index
After: {"ams_id": 255, "slot_id": 0} <- correct slot index
This caused prints using external spool to fail immediately with error
code 07FF_8007.
Closes#213
Bambu Studio converts spaces to underscores when saving files to the
printer, but MQTT reports the original name with spaces. This caused
FTP downloads to fail with "550 Failed to open file" because we were
searching for "Battery Storage_giesela.gcode.3mf" but the actual file
was "Battery_Storage_giesela.gcode.3mf".
Changes:
- Add underscore variants to direct download path attempts
- Normalize spaces/underscores in fallback directory search
- Apply fix to archive download, cover extraction, and objects reload
Closes#218
