fix: resolve all lint errors in e2e tests and improve type safety

- Replace 'any' types with proper TypeScript interfaces in auth setup/teardown
- Remove conflicting custom Playwright type declarations that were overriding official types
- Fix ES module compatibility by replacing require() with proper import paths
- Add proper generic typing to Playwright test fixtures
- Fix test discovery in auth debug configuration
- Add comprehensive auth debug setup documentation

Fixes:
- 3 lint warnings about explicit 'any' usage
- 45+ TypeScript compilation errors from type conflicts
- ES module import errors in auth configuration
- Test fixture typing issues

All e2e tests now pass lint and type checking with zero warnings.
