0580aec7b0 harden OTP for real SMS and close the second audit round
Kavenegar is being switched on, so every OTP request now costs credit:
- phone numbers are normalised to 09XXXXXXXXX everywhere (login, OTP,
  family invite, TEST_LOGIN_PHONES keys) and existing rows are migrated;
  non-Iranian and landline numbers are rejected before any SMS
- cooldown and a daily per-phone cap are counted in the database, so the
  three gunicorn workers no longer triple them
- a global daily OTP SMS cap (default 300) stops SMS pumping
- per-IP rates widened for CGNAT / school Wi-Fi (env-overridable)
- provider message id is logged; SMS text warns not to share the code

Second audit round: an offer no longer shortens a longer paid plan,
Zarinpal error bodies no longer 500, island XP reaches the parent report,
a non-numeric questionId no longer 500s after the answer is generated.

596 tests green.

42783f9ba4 tutor answers step by step in plain text, islands finish, and the audit's money and login holes are closed
Tutor (prompt tutor-v3-stepwise-plain): plain text instead of LaTeX/markdown,
with rag/services/mathtext.py converting whatever still slips through; full
step-by-step solutions with a check before the final answer; three tones by
grade; the last 6 messages of the conversation go to the model and follow-ups
are no longer served from another user's cache; book solutions the checker
disputes are kept out of the context; a questionId gives the tutor the
practice question and the student's wrong answer. /api/health reports when
the AI credit runs out. rag_model_benchmark compares chat models on verified
book problems (run on the server; credit ran out mid-run).

Map: only lessons that have questions count toward finishing an island,
lessonIds[0] / nextLessonId is always the next lesson to play, and a finished
island stays finished. The Seyar characters (sigma/delta/pi) are seeded.

Audit fixes, each reproduced before fixing:
- the plan is stored on the order, so paying a monthly order after starting
  a yearly checkout no longer grants a year
- opening checkout no longer demotes an active subscription; renewals extend
  from the current expiry; expired subscriptions are not reported active
- one discount code per order and only before the gateway; a 100% code
  completes the purchase; lost Zarinpal confirmations are re-verified
- the unused /api/payment/webhook "mark paid" endpoint is removed
- XP counts only answers recorded on the server
- 6-digit OTP, each code dies after 5 wrong guesses; POST /api/auth/logout
- a guest who signs up keeps their account and progress (test phones excluded)
- affiliate commission on the first real payment; guests excluded
- parents with several children no longer get a 500
- SQLite runs transactions IMMEDIATE, since it ignores select_for_update
- admin login is rate-limited; display names drop phone numbers and links;
  userQuestion is capped at 2000 characters
- server-side heart enforcement exists behind HEARTS_ENFORCED (off until the
  frontend handles 403 no_hearts)

Not done on purpose: rotating the server's secret key and moving to Postgres.

5aa10eb7b7 give every developer a way into the API that does not depend on one person
With DEBUG=0 and Kavenegar unconfigured, POST /api/auth/otp/request returns a
hard 503, so the only way to sign in was for someone with admin access to hand-
create an OTPCode row. That made every frontend developer's login depend on one
person being available.

TEST_LOGIN_PHONES is the pattern real apps use for exactly this (Firebase Auth's
fictional numbers, Apple's App Store demo account): a short allowlist of
phone:code pairs that skip SMS delivery entirely. Unlike DEV_MASTER_OTP it is
not "any phone with one code" and it is not tied to DEBUG -- each number carries
its own code, and everything else takes the normal OTP path untouched.

The code never appears in an API response, so knowing the number is not enough
to log in, and the existing per-phone login attempt limit still applies, so the
code cannot be brute-forced. Malformed configuration raises ImproperlyConfigured
at startup rather than being skipped silently, and /api/health reports how many
test numbers are open (count only) so they cannot be forgotten on a server that
has real users.

The code is capped at six digits because LoginRequestSerializer caps otp at
max_length=6; a longer code would have been rejected before reaching the check
and looked like the feature was broken.

The guest path the frontend uses today is untouched, and leaving the variable
empty reproduces the previous behaviour exactly.

5f3aae0756 cover the new paths, especially the ones that fail silently
خطاهای این پروژه خاموش‌اند: نامِ اشتباهِ collection یا فیلترِ نخورده نتیجه‌ی
خالی می‌دهد نه استثنا، و دستیار فقط بدتر جواب می‌دهد. این تست‌ها نگهبانِ
همان‌جاهایند.

TextbookLayoutTests بررسی می‌کند رشته‌ی هر فصل بینِ ingest و retrieval یکی
باشد و بازه‌ی صفحه‌ها پیوسته بماند. IngestBookResumeTests مطمئن می‌شود
صفحه‌ی بی‌مسئله دوبار پول نمی‌گیرد، صفحه‌ی خطادار در اجرای بعد دوباره
سراغش می‌روند، و upsertِ شکست‌خورده rollback می‌شود.
LessonContextResolutionTests نگهبانِ نرمال‌سازیِ «پایه نهم» → «ریاضی نهم»
است و اینکه مسیرِ gradeId و مسیرِ lessonId به یک collection برسند.
GradeAwarePromptTests جلوی برگشتنِ لحنِ دبستانی برای پایه‌های بالا را
می‌گیرد. FollowUpStaysGroundedTests پیامِ دومِ یک گفتگو را هم مستند نگه
می‌دارد.

d25ecab0b3 optional short-TTL cache for the auth user row
TadrisinoTokenAuthentication ran one SELECT on accounts_user for every
authenticated request. Off by default (AUTH_USER_CACHE_TTL=0) so behaviour
is unchanged until a deployment opts in.

accounts/authentication.py
  - _get_request_user(): when AUTH_USER_CACHE_TTL>0, cache all concrete
    field values under auth:user:<id> and rebuild a full User instance
    (so save(update_fields=[...]) stays safe); otherwise load from DB as
    before. invalidate_user_cache() / _load_user_or_fail() helpers.
accounts/receivers.py (new)
  - post_save/post_delete on User -> invalidate_user_cache(pk); covers
    every in-app write path (SetUserGrade, login, refresh, last_activity).
accounts/apps.py
  - AccountsConfig.ready() imports receivers.
accounts/tests.py
  - AuthUserRowCacheTests: disabled -> loads every request; enabled ->
    loads once then cache; User.save() invalidates; SetUserGradeView still
    persists and the next request sees the new grade.
