feat: add CSRF protection for admin API routes

Double-submit cookie pattern: login sets bh-csrf-token cookie,
proxy.ts validates X-CSRF-Token header on POST/PUT/DELETE to /api/admin/*.
New adminFetch() helper in src/lib/csrf.ts auto-includes the header.
All admin pages migrated from fetch() to adminFetch().

## Brand / Styling
- **Accent**: rose/red (`#e11d48`)
- **Dark mode**: bg `#0a0a0a`, surface `#171717`
- **Light mode**: bg `#fafafa`, surface `#ffffff`
- Logo: transparent PNG, uses `dark:invert` + `unoptimized`

- **Background**: `#050505` `#0a0a0a` (dark only)
- **Surface**: `#171717` dark cards
- Logo: transparent PNG heart with gold glow, uses `unoptimized`
## Content Data
- All text lives in `src/data/content.ts` (type-safe, one file to edit)
- 13 team members with photos, Instagram links, and personal descriptions
- Primary source: SQLite database (`db/blackheart.db`)
- Fallback: `src/data/content.ts` (auto-seeds DB on first access)
- Admin panel edits go to DB, site reads from DB via `getContent()`
- 12 team members with photos, Instagram links, bios, victories, education
- 6 class types (Exotic Pole Dance, Pole Dance, Body Plastic, etc.)
- Master classes with date/time slots and public registration
- 2 addresses in Minsk, Yandex Maps embed with markers
- Contact: phone, Instagram
- Contact: phone, Instagram (no email)
## Admin Panel
- Password-based auth with HMAC-SHA256 signed JWT (24h TTL)
- Cookie: `bh-admin-token` (httpOnly, secure in prod)
- Auto-save with 800ms debounce on all section editors
- Team members: drag-reorder, photo upload, rich bio (experience, victories, education)
- Master classes: slots, registration viewer, trainer/style autocomplete from existing data
- File upload: whitelisted folders (`team`, `master-classes`, `news`, `classes`), max 5MB, image types only
## Security Notes
- **CSRF protection**: Double-submit cookie pattern. Login sets `bh-csrf-token` cookie (JS-readable). All admin fetch calls use `adminFetch()` from `src/lib/csrf.ts` which sends the token as `X-CSRF-Token` header. Middleware (`proxy.ts`) validates header matches cookie on POST/PUT/DELETE to `/api/admin/*`. **Always use `adminFetch()` instead of `fetch()` for admin API calls.**
- File upload validates: MIME type, file extension, whitelisted folder (no path traversal)
- API routes validate: input types, string lengths, numeric IDs
- Public MC registration: length-limited but **no rate limiting yet** (add before production)
## AST Index
- **Always use the AST index** at `memory/ast-index.md` when searching for components, props, hooks, types, or styles
- Contains: component tree, all exports, props, hooks, client/server status, CSS classes, keyframes
- Covers all 31 TS/TSX files + 4 CSS files
- Update the index when adding/removing/renaming files or exports
