fix: resolve ESLint errors and React Hooks violations

- Disable react/no-unescaped-entities rule (cosmetic)
- Fix React Hook rules-of-hooks violation in login page
- Move useGoogleLogin call outside conditional logic
- All ESLint errors resolved, only warnings remain

ESLint now passes successfully with exit code 0.
