Lesson files were served inline (no Content-Disposition) → browsers
opened PDFs in a new tab instead of downloading; flaky across
browsers/providers. Set Content-Disposition: attachment with the
human-readable filename (RFC 5987 for Cyrillic) on upload.

- /api/internal/grant: secret-auth endpoint for payment-router to
provision access on a paid order — find-or-create user (emailVerified,
temp password, mustChangePassword), enroll by course slug list,
AccessLog, delivery email. Idempotent by order_id.
- User.mustChangePassword flag (+ migration); (student) layout redirects
flagged users to /change-password (forced first-login change).
- email.ts: sendCourseGrantEmail (temp password for new buyers).
- middleware: /api/internal is public (own secret auth).

requireEmailVerification was enabled but no sendVerificationEmail was
configured — new users saw "check your email", never received anything,
and couldn't log in (403 shown as "wrong email or password").
- email.ts: add verification email template; welcome email no longer
claims the account is "confirmed"
- auth.ts: configure emailVerification (send on signup, resend on
unverified login attempt, auto sign-in after verification, 24h TTL)
- register route: callbackURL=/dashboard so the verify link lands in
the cabinet
- login form: distinguish 403 (unverified — tell user a fresh link was
sent) and 429 (rate limit) from wrong credentials

- Backend: explicitly return 409 EMAIL_TAKEN when the email already
exists, instead of Better Auth's silent 200 (common after migration).
- Frontend: split error handling — network failure, non-JSON body
(502/proxy), and meaningful server errors get distinct messages; the
"email already registered" case shows login / reset-password links
instead of a generic "connection error".

- Add coverImage field to Lesson model (prisma)
- Pass coverImage as poster prop to KinescopePlayer
- Show quiz in read-only preview mode for admin on lesson page
- Fix TipTap v3 editor reset on save: pass [lesson.id] as deps to useEditor
to prevent setOptions() from reinitializing content on every re-render
- Replace saveLesson Server Action call with fetch PATCH /api/admin/lessons/[id]
to avoid Next.js 16 automatic RSC refresh after Server Actions
- Simplify revalidatePath: only revalidate module page, not lesson editor page
POST /api/admin/lesson-files now checks for an existing record with the
same (lessonId, name) before uploading — replaces it (old S3 object
deleted) instead of always creating a new one. Previously every save
cycle accumulated an extra copy; 1183 duplicates occupying 6.5 GiB were
found and cleaned up.
DELETE now receives the file URL and extracts the S3 key from it, so
manual deletion actually removes the object from storage.
