fix: resolve all ESLint errors and TypeScript compilation errors

- Auto-fixed 712 import ordering errors via `pnpm lint --fix`
- Manually fixed 13 remaining ESLint errors:
  - Prefixed unused vars with _ (mockAdminUser, params)
  - Removed unused imports (UnauthorizedException, vi, screen)
  - Moved imports above vi.mock() calls to fix import group ordering
  - Removed eslint-disable for non-existent rules
  - Fixed empty object pattern in Playwright fixture
- Fixed ~40 TypeScript TS4111 index signature errors in test files:
  - Used bracket notation for Record<string, unknown> property access
  - Added missing PropertyMedia fields (id, order, caption) to test data
- Fixed pre-existing test failures in rate-limit guard specs:
  - Added NODE_ENV override to bypass test-mode skip in guard

Both `pnpm lint` and `pnpm typecheck` now exit 0 cleanly.
