feat: complete CalDAV (RFC 4791) and CardDAV (RFC 6352) implementation
- CalDAV: MKCALENDAR, PROPFIND, PUT/GET/DELETE events, REPORT calendar-query
- CardDAV: MKCOL, PROPFIND, PUT/GET/DELETE vCards, REPORT addressbook-query
- Fix routing: move CalDAV/CardDAV to top-level merge() with explicit routes
- Fix DB schema: VARCHAR(36) -> UUID for entity IDs, vcard_data -> vcard
- Fix 15 repository stub methods that returned empty results
- Fix vCard parser in ContactStorageAdapter (was hardcoded stub)
- All operations tested end-to-end in Docker (201/207/200/204 as expected)
