refactor(phase2a): Extract auth + public blueprints with Alias Bridge
Phase 2a of modular monolith refactoring:
New blueprints:
- blueprints/auth/routes.py (1,040 lines, 20 routes)
- login, logout, register, verify_2fa, settings_2fa
- forgot_password, reset_password, verify_email
- konto_dane, konto_prywatnosc, konto_bezpieczenstwo, konto_blokady
- blueprints/public/routes.py (862 lines, 11 routes)
- index, company_detail, person_detail, search
- dashboard, events, new_members, release_notes
Alias Bridge strategy:
- Both url_for('login') and url_for('auth.login') work
- Templates don't require changes (backward compatible)
- Original routes in app.py marked with _old_ prefix (dead code)
Next step: Cleanup dead code from app.py after production verification
