fix(camera): share one ffmpeg connection for /api/camera/stream

Manually integrated from PR #91 (Pavulon87) - the PR branch itself had
unresolved git conflict markers in handle_camera_stream from a stale
rebase against nightly, so it couldn't be merged directly.

/api/camera/stream previously spawned a dedicated ffmpeg process and
printer connection per HTTP client. The printer only tolerates a very
limited number of concurrent camera connections, so two simultaneous
viewers (dashboard + a Moonraker client, two browser tabs, ...) could
already exhaust that limit and cause intermittent 429/"stream
unavailable" failures.

Adds a third CameraCache fanout channel (mjpeg_subscribers), mirroring
the existing h264 pattern, so all /api/camera/stream consumers share one
ffmpeg process. Also carries over two related fixes found in the PR:
ensure_running() checked self._proc_* instead of self._task_*, leaving a
race window where two callers could each spawn a duplicate ffmpeg
process before the first task got scheduled; and reset() didn't cancel
the owning task, so a loop stuck in its exponential backoff sleep (up to
300s) wouldn't restart immediately.

 ## [Unreleased]
 
 ### Fixed
+- **Slot kept showing/printing a stale filament type after a spool swap.** The
+  per-slot profile override (config.ini `[filament_profiles]`) stores only
+  vendor+name and was sticky: swapping the physical filament updated the AMS
+  colour and type live, but the saved profile persisted, so a slot that held
+  e.g. "KINGROON PETG Basic" kept showing/sending PETG in the panel and the
+  OrcaSlicer lane hint even after yellow PLA was loaded — and survived restarts.
+  The override is now applied only while its material *family* still matches the
+  loaded AMS material (PLA / PLA+ / PLA SILK / PLA MATTE are one family, so
+  within-family swaps never invalidate a valid profile). On a family change the
+  slot falls back to the generic default; the override is not deleted, so
+  reloading the original material reactivates it.
 - **Filament profiles not isolated between printers in a multi-printer bridge**
   (issue #74). The slot→profile mapping and `visible_vendors` were stored in a
   single global `[filament_profiles]` section, so configuring one printer

 ## Changes in this build
 
-- Refactor: all logs, comments and API error strings translated to English across the codebase (no behavior change)
-- Refactor: the `print/start` payload was duplicated in three places and had drifted (the new resonance-compensation setting was missing from the upload+print path) — all print start paths now share one payload builder
-- Fix: a couple of silently swallowed errors (dashboard reprint filament-cache load, filament metadata backfill) now log a warning/debug message instead of failing silently
-
-**A stable release is coming soon** with the fixes and features from the last several nightly builds. As usual it will be published as ready-to-run binaries (Linux amd64/arm64, Windows) alongside the Docker image.
+- Fix: dashboard reprint from the cache path crashed with an AttributeError (`self._db` did not exist) instead of applying the filament slot filter (PR #93, thanks @Pavulon87)
+- Feat: the dashboard now shows a banner with the reason and error code when a print is paused, with a direct link to the Anycubic error-code docs (PR #92, thanks @Pavulon87)
+- Fix: `/api/camera/stream` (the MJPEG live view used by the dashboard and every Moonraker-compatible client) opened a brand-new ffmpeg process and printer connection per HTTP client — two simultaneous viewers could already exhaust the printer's very limited camera connection slots and cause intermittent "stream unavailable"/429 failures. All consumers now share one ffmpeg process via the same fanout pattern already used for the H.264 stream (credit to @Pavulon87 for the fix and for finding two related race conditions along the way)

+"""Stale slot-profile guard: suppress a saved per-slot filament profile when the
+AMS now reports a *different material family* than the profile was assigned for.
+
+Real-world bug (KX1): slot 1 held a PETG spool and got the profile
+"KINGROON PETG Basic". The user swapped in yellow PLA. The AMS updated the
+colour (live) but the saved profile stuck on PETG, so the panel + the slicer
+hint kept showing/using PETG. Restarting did not help — the override lives in
+config.ini.
+
+Fix = non-destructive suppression (Option A): resolve the effective profile as
+"the saved override only if its material *family* matches the current AMS
+material; otherwise none (fall back to the generic default)". The override is
+never deleted, so putting the original material back reactivates it.
+
+Comparison must be by *family*, never strict string equality — PLA / PLA+ /
+PLA SILK / PLA MATTE are the same family and must NOT invalidate each other
+(regression guard for the earlier over-strict material compare).
