Refactor password reset flow and improve ESLint integration

- Extracted password reset logic into `PasswordResetConfirmContent` wrapped in `Suspense` for cleaner and more modular component structure.
- Updated ESLint config to ignore generated files and added rules for stricter code quality (`eslint-comments`, `@typescript-eslint` adjustments).
- Automated insertion of `eslint-disable` in auto-generated TypeScript files through `generate-api-client.sh`.
- Replaced unsafe `any` type casts with safer `Record<string, unknown>` type assertions for TypeScript compliance.
- Added `lint:tests` script for pre-commit test coverage checks.
- Improved `useAuth` hooks and related type guards for better runtime safety and maintainability.
