Add /cookies/check to youtube-downloader and instagram-downloader,
polled every 30 min from bot.py; alerts the admin bot on
healthy->broken transitions (with a 24h re-reminder cap while still
broken) and on recovery. Also stop leaking raw exception text to end
users - they now see a plain, friendly English message while the
admin bot still gets full technical detail via notify_admin_error.
Notify admin (URL + error text + user info) on any download failure
across all sources, and on the file-too-large case, mirroring the
existing successful-download notification.

chat_id is shared by every member of a group chat, so all group
messages incremented one shared row and username kept getting
overwritten by whoever sent last. Track link counts in a new
user_links table keyed by the real from_user.id instead.
Adds users.link_count, incremented in bot.py whenever a user submits
a recognized link (regardless of eventual download success), and
surfaces it in admin_bot's /stat as a count of users who ever sent a
link plus a top-5 leaderboard by link count.
send_video_to_admin_bot() had no retry, unlike the client-facing
reply_video() path fixed earlier — a transient httpx.ReadError during
upload silently dropped the admin copy while the user still got their
video, since this function swallows its own exceptions.
EXTRACTOR_ARGS used ':' instead of ';' between player_client and skip
fields, so yt-dlp parsed "android:skip=translated_subs" and "hls" as
bogus player_client values and silently fell back to the web client
only, which fails the n-challenge and returns no formats.
--max-requests=1 fully restarted the gunicorn worker after every
single request, opening a race window that could drop the response
connection right after a successful download; raised to 20 with
jitter to keep the periodic-recycle safety net without doing it on
every request.
reply_video() to Telegram had no retry, so a transient httpx
transport error during upload discarded an already-downloaded video;
added the same 3-attempt retry pattern already used for the
downloader services.
