CarlandClaude Sonnet 5 24863203fb fix(camera): sweep orphaned timelapse session directories on startup ...

_active_sessions is in-memory only, so a process restart mid-print
loses track of any active layer-timelapse session without ever calling
cancel_session()/cleanup() - the frames directory (and, if stitching
had already produced output before the restart, a stray
timelapse_<session_id>.mp4) are then orphaned on disk permanently, with
no equivalent to the ffmpeg orphan janitor to reap them.

Confirmed live: 38MB of exactly this leftover on the OrangePi after
several restarts during this week's testing, including two corrupt
48-byte .mp4s from stitches that got interrupted mid-write.

Adds cleanup_orphaned_timelapse_sessions(), run once at startup: for
each printer_id under timelapse_frames/, remove any frame directory or
stitched-output file that doesn't match that printer's current active
session (if any) and is older than a defensive margin (5 min default).
A restart-recovered print never gets a new timelapse session either
(#1353's _maybe_start_layer_timelapse only fires on fresh PRINT_START
events), so nothing orphaned here can ever be resumed - safe to always
remove once it's old enough not to be a startup race.
