Mejoras de estabilidad de stream IPTV y nuevo registro de fallos

- restream.py: eliminar -reconnect_streamed de ffmpeg para evitar rebobinados
  al reconectar (el proveedor re-enviaba desde keyframe anterior causando PTS
  backward). El loop de Python gestiona las reconexiones con conexión fresca.
- restream.py: eliminar _drain_queue del loop de reconexión para que el buffer
  de la cola cubra el tiempo de reconexión sin pantalla negra en el player.
- restream.py: añadir buffer_server_bytes/secs/capacity a stats() y método
  _log_stream_event() para persistir eventos de caída y recuperación en BD.
- models/stream_event.py: nuevo modelo StreamEvent para registro de fallos.
- database.py: registrar StreamEvent en init_db.
- api/admin/logs.py: nuevos endpoints GET/DELETE /logs/events.
- Dashboard.tsx: mostrar reserva de buffer del servidor (capacidad + estado).
- Logs.tsx: añadir pestaña "Fallos de stream" con tabla de eventos persistidos.

+"""BroadcastGroup: fan-out a single provider stream to N simultaneous clients.
+
+Recovery model
+--------------
+The pump loop runs indefinitely while self._running is True.  Each iteration
+spawns an ffmpeg process in copy (remux) mode.  ffmpeg owns the upstream
+HTTP connection.  When the provider closes the session (typically every
+~2 minutes) ffmpeg exits and the outer loop spawns a fresh process — the
+provider delivers from the current live edge so timestamps are always
+forward-moving and the player never sees a backward seek (rewind).
+
+If ffmpeg itself exits (unrecoverable error or stall beyond its own timeout)
+the outer loop drains all client queues, backs off briefly, and spawns a
+fresh ffmpeg process — again without disconnecting clients.
+
+SENTINEL is only pushed when stop() is called or the pump truly gives up.
+
+Stall detection
+---------------
+ffmpeg's -timeout option (socket-level read timeout) handles provider stalls.
+A safety-net asyncio.wait_for wraps each stdout read in case ffmpeg hangs
+without producing output or exiting.
+
+A/V sync
+--------
+ffmpeg re-muxes the incoming MPEG-TS into a fresh output stream.  On every
+reconnect the output PTS/DTS sequence is continuous regardless of provider-
+side timestamp resets, eliminating audio desync entirely.  No video or audio
+is re-encoded — quality is bit-for-bit identical to the source.
