johndoe6345789 2125e5efe7 chore: Code review - fix critical bugs and lint errors
Key changes:
1. Fix critical bug in src/app/page.tsx: removed conflicting `export const dynamic` that shadowed imported `dynamic` from next/dynamic, causing ReferenceError at runtime. Replaced with `export const revalidate = 0` then removed (client component).

2. Install missing typescript-eslint dependency and fix ESLint configuration to use flat config format properly.

3. Fix 32 ESLint errors across codebase:
   - Remove unused variables and imports (concat unused props in components)
   - Replace `any` types with proper TypeScript types (React.MutableRefObject)
   - Change empty interface in textarea.tsx to type alias
   - Fix react-hooks rule name from non-existent `set-state-in-effect` to `exhaustive-deps`

4. Code quality improvements:
   - Removed unused cn import from aspect-ratio.tsx
   - Removed unused useRef, useEffect from sheet.tsx imports
   - Simplified handler parameters in avatar.tsx
   - Cleaned up test files (removed unused container/user variables)

Results after review:
- Unit tests: 275 passing, 14 failing (improved from 270/19)
- E2E tests: 204 passing, 59 failing, 17 skipped (now running after critical fix)
- Linter: 0 errors (all 32 fixed)
