The frontend plays node quizzes, but a node only completed once every one of its
8-13 lessons was completed separately, so students were stuck after the first
island of each unit. POST /api/nodes/{id}/quiz/complete now completes the node
(any score; score only sets stars/xp) and returns nextNodeId.
Also closes the other backend gaps found while auditing the frontend:
- /api/ai/ask without lessonId now picks the book from the user's grade instead
of skipping retrieval, so the "ask Pi" tab is grounded in the textbook.
- guest sessions return a refreshToken; they used to go silently 401 after 1h.
- lesson_complete throttle 10/hour -> 120/hour (a lesson here is 1-2 questions).
- progressPercent is per grade, not over all 2,617 lessons of every grade.
- a one-year plan (299,000 toman) is created by migration when no plan exists.

کارتِ اشتراک زیرِ هر پلن فهرستِ امکانات و یک برچسب («محبوب‌ترین»، «بهترین
ارزش») نشان می‌دهد، و هر دو در کدِ فرانت هاردکد بودند — یعنی عوض کردنِ یک
بندِ متنی به دیپلویِ تازه‌ی اپ نیاز داشت.
Plan حالا features و badge دارد. `popular` سرِ جایش ماند: بولین است و متنِ
برچسب را نمی‌دهد، پس این جایگزینش نیست، کنارش است. هیچ‌کدام اجباری نیستند و
پلن‌های موجود بدونشان همچنان سرو می‌شوند.

next_refill_at was set on UserHearts but never read or recalculated,
so a heart lost to zero never came back. UserHearts.apply_regen() now
catches up missed 24h intervals on read/deduct, and lose_heart() starts
the timer only when it isn't already running.
Any user with an active (non-expired) subscription now skips heart
deduction entirely, regardless of which plan they're on — good enough
for now until per-plan perks are needed.
