Reported in #881, where the reporter had to reverse-engineer this from
the outside over several days: setting
YTDL_OPTIONS={"cookiefile": "/cookies/cookies.txt"} appeared to do
nothing whenever a cookies file had also been uploaded through the UI.
Uploaded cookies winning is correct and stays as it is. The upload
exists so cookies can be refreshed without restarting the container, and
letting YTDL_OPTIONS win instead would leave a visible UI button that
silently does nothing.
The defect is that it happened in silence, and could not be reported
afterwards even in principle. set_runtime_override writes into
YTDL_OPTIONS directly, so the moment an uploaded file is applied the
configured path is gone from the live config: delete_cookies' existing
has_manual_cookiefile check compares against COOKIES_PATH and therefore
cannot fire once the value has been replaced. The two override points
are the only places where both paths are still visible, so that is where
the warning has to go.
The startup path previously logged only "Cookie file detected"; both it
and the upload handler now say plainly which file is being ignored and
how to get it back.

Addresses a full-project review. Backend correctness and availability:
- ytdl: cancel() only SIGKILLs the child's process group when the child
actually became its own group leader, so a race (or failed setpgrp)
can no longer kill the whole server; kill the group on cancel and on
shutdown to avoid orphaned ffmpeg children
- ytdl: dedicated ThreadPoolExecutor for download supervision so active
downloads can't starve extract_info / live probes on the default pool
- ytdl/main/subscriptions: route fire-and-forget tasks through a
bg_tasks helper that keeps a strong ref and logs failures
- subscriptions: run flat-playlist extraction in an executor and check
feeds with bounded concurrency so one slow feed can't block the loop;
set last_checked on failure so broken feeds aren't retried every 60s
- main: validate ids on /start & /delete and numeric env vars at startup;
return 400 (not 500) on bad subscriptions/update input; serve /history
from memory; move get_custom_dirs off the event loop; restrict t=
stripping to YouTube hosts; drop double percent-decode in state guard
- dl_formats/ytdl: enforce requested caption format via
FFmpegSubtitlesConvertor and strip VTT header metadata only in the
pre-cue region so real dialogue is preserved
- ytdl: throttle progress events, dedup adds against pending, clear
filename/size on error and reject out-of-dir trashcan deletes, pin
fork start-method on Linux only
Frontend:
- retry deletes the done record only after a successful re-add
- surface HTTP errors for delete/start and reset the deleting flag
- ignore late 'updated' events for rows no longer in the queue
- track table rows by map key; FileSizePipe uses base-1024
Also: HTTPS-aware Docker healthcheck, dead-code removal, and shared
helpers for path-containment and yt-dlp option merging. Adds/updates
unit tests throughout (250 backend tests passing).
