Fix SSR errors, enhance Person activity views, and expand Core CRUD

- Resolved Svelte 5 / SvelteKit SSR errors by adding browser checks for window.postMessage and Dexie database operations
- Prevented side effects on global state during detail page preloading by refactoring people/[person_id]/+page.ts to use shallow copies
- Implemented full V3 CRUD support, detail pages, and editable_fields for Address and Contact modules
- Enhanced Event and Post search to support filtering by person_id, enabling real related data in the Person detail view
- Fixed missing onMount import in Person detail component
