maziggy 5b0a985da2 Add explanatory comments to 265 empty except blocks 
CodeQL flags except blocks where `pass` has no comment explaining
why the exception is silently ignored (py/empty-except rule).

Added context-specific comments to all 265 instances across 31 files:
- database.py (~112): ALTER TABLE migrations — "Already applied"
- archive/library/3MF parsing (~64): "Skip unparseable metadata"
- virtual_printer network cleanup (~32): "Best-effort socket cleanup"
- discovery/SSDP (~13): "SO_REUSEPORT not available" / socket cleanup
- bambu_ftp/mqtt (~13): FTP cleanup, JSON decode, signal parsing
- remaining routes/services (~31): context-specific comments

maziggy 53bd4fadb3 Fix safe security findings: hashlib, log injection, broad excepts 
- Add usedforsecurity=False to MD5 (AMS fingerprint) and SHA1 (git blob
  hash) calls to silence Bandit B303 / CodeQL weak-crypto findings
- Convert ~996 f-string logging calls to parameterized %s-style across
  55 files to prevent log injection (Bandit G201 / CodeQL log-injection)
- Narrow ~199 broad except Exception blocks to specific types:
  OperationalError for DB migrations, OSError for network/file cleanup,
  (OSError, ftplib.error_reply) for FTP, and targeted tuples for
  ZIP/XML/JSON parsing — 36 intentionally left broad (mixed async,
  re-raise patterns)

maziggy 81d18cb8bd Virtual Printer Proxy Mode Improvements 
- SSDP proxy for cross-network setups: select slicer network interface for automatic printer discovery via SSDP relay
- FTP proxy now listens on privileged port 990 (matching Bambu Studio expectations) instead of 9990
- For systemd: requires `AmbientCapabilities=CAP_NET_BIND_SERVICE` capability
- Automatic directory permission checking at startup with clear error messages for Docker/bare metal

maziggy 88e84ca45a - Add Virtual Printer feature - emulate Bambu printer on network 
- Virtual printer appears in Bambu Studio/Orca Slicer via SSDP discovery
  - Secure TLS/MQTT communication with auto-generated certificates
  - Queue mode (pending uploads) or auto-start mode
  - Configurable access code for authentication
  - Docker support with network_mode: host and certificate persistence
  - Fix backup/restore for virtual printer settings (auto-save no longer overwrites)
