maziggy abc8e97050 feat(camera): optional snapshot URL override for external cameras (#1177) 
go2rtc and several IP cameras still emit a warm-up / black frame on every
  fresh MJPEG connection — even with the v0.2.4b2 warm-up-skip fix it
  slipped through intermittently for @nkm8's setup. His own bisect named
  the clean solution: go2rtc exposes /api/frame.jpeg as a dedicated
  single-frame endpoint that never returns the encoder's stale keyframe.

  Adds an optional external_camera_snapshot_url column on printers. When
  set, every single-frame capture path (snapshot endpoint, [SNAPSHOT]
  notification thumbnails, [PHOTO-BG] finish photo, layer timelapse,
  Obico ML, plate-detect / calibrate-plate) routes through _capture_snapshot
  on the override URL via plain HTTP GET, bypassing the warm-up dance.

  Live view stays on the configured stream URL — only single-frame
  captures use the override. Override is camera-type-agnostic. SSRF guard
  applies (existing _sanitize_camera_url allowlist). Empty string treated
  as unset.

  Settings UI: new "Snapshot URL (optional)" input + Test button under
  External Cameras, hidden for camera_type=snapshot since the live URL is
  already a single-frame source. en + de fully translated; 6 other locales
  seeded with English copy.

  5 backend tests pin the routing contract; 3 frontend tests pin the
  input + debounced PATCH. Documented in
  bambuddy-wiki/docs/features/camera.md with the go2rtc example.

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 691fb133b7 Add external network camera support for printers 
Add support for external network cameras (MJPEG, RTSP, HTTP snapshot)
that replace a printer's built-in camera when configured.

Features:
- Live streaming on printers page (replaces built-in camera)
- Finish photo capture from external camera on print complete
- Layer-based timelapse: captures frame on each layer change,
  stitches to MP4 video on print completion

Backend changes:
- Add external_camera_url, external_camera_type, external_camera_enabled
  fields to Printer model with database migration
- New external_camera.py service: MJPEG/RTSP/snapshot frame capture,
  connection testing, MJPEG stream generation
- New layer_timelapse.py service: TimelapseSession management,
  layer-by-layer frame capture, ffmpeg video stitching
- Add on_layer_change callback to MQTT client and printer manager
- Update camera routes with external camera streaming and tracking
- Update print lifecycle hooks for timelapse start/stitch/cancel
- Add external camera fields to backup/restore
- Rate limiting for external camera streams (prevents browser freeze)

Frontend changes:
- Add external camera configuration UI in Settings > Camera
- Per-printer enable toggle, URL input, type selector, test button
- Toast notification on save

Closes #143
