captioner: set_caption_detail now marks CAPTION_SESSION_DIRTY so the
cached FlorenceCaptioner session is torn down and rebuilt with the new
prompt and token limit; previously only the file was updated on disk
db: reset_generated_captions now cancels in-flight caption jobs instead
of deleting them; the worker checks for a cancelled row before writing
back, so deleting the row allowed results to be written immediately after
a reset — now mirrors the clear_caption_jobs cancellation protocol
BackgroundTasks: caption_pending/ready/failed counts are now included in
pendingMediaWork, task stages, hasFailed checks, and the dismiss snapshot;
previously a folder with only caption work caused the panel to disappear
entirely and exposed no caption progress or failure status
