Production is ArvanCloud -> nginx -> gunicorn, but NUM_PROXIES was 1, so DRF
took ArvanCloud's edge IP as the client: every guest and every OTP request
behind one edge shared a single throttle bucket (20 guest sessions an hour for
everyone). Default is now 2, and /api/health reports clientIp so the proxy
count can be checked from outside.
PATCH /api/notifications/read-all replaces the frontend's one-PATCH-per-item
loop, which spent the shared "read" budget 75 requests at a time.

Three gaps found while seeding test data for the frontend, all of the same
kind: a contract that looks complete from the outside and is empty underneath.
Nothing in the codebase ever wrote a LeaderboardEntry. Not a signal, not a
service — only the admin form and seed_test_data. So /api/leaderboard returned
`entries: []` forever on any real server, and any row put there was a frozen
number that never tracked activity. rebuild_leaderboard now derives both
periods from real XP: all_time from UserStats.xp, weekly from a sum over
content.UserLessonCompletion in a window. It deliberately does not count
UserAnswer.xp_earned — that field is written but never added to UserStats, so
summing both would report roughly double. deploy.sh runs it every release;
a cron is the real answer once traffic is real, and the script says so.
'lesson_completed' was declared in Notification.TYPE_CHOICES but nothing
called notify() with it, so finishing a lesson produced no notification at
all. LessonCompleteView now emits one, on first completion only (the same
condition that grants xp/coins), inside the completion transaction so a lost
notification cannot leave a silent half-done state.
The notification list serializer returned only id/type/title/isRead. body and
created_at were on the model from the start but never exposed, so the frontend
had neither the text of a notification nor its time. Both added; the change is
purely additive, so the existing client keeps working.
472 tests green, up from 458. makemigrations --check, check and spectacular
are all clean.
