feat: add security event taxonomy and optimize park queryset
- Add comprehensive security_event_types ChoiceGroup with categories for authentication, MFA, password, account, session, and API key events
- Include severity levels, icons, and CSS classes for each event type
- Fix park queryset optimization by using select_related for OneToOne location relationship
- Remove location property fields (latitude/longitude) from values() call as they are not actual DB columns
- Add proper location fields (city, state, country) to values() for map display
This change enhances security event tracking capabilities and resolves a queryset optimization issue where property decorators were incorrectly used in values() queries.
- Introduced a comprehensive Secret Management Guide detailing best practices, secret classification, development setup, production management, rotation procedures, and emergency protocols.
- Implemented a client-side performance monitoring script to track various metrics including page load performance, paint metrics, layout shifts, and memory usage.
- Enhanced search accessibility with keyboard navigation support for search results, ensuring compliance with WCAG standards and improving user experience.
