Add Community license configuration in static constructor, matching

the existing pattern in EmergencyKitPdfService. Without this, QuestPDF

throws on PDF generation since it requires explicit license selection.

New test areas covering previously untested functionality:

• Sync ledger: list_all_entity_ids, entities_needing_sync (with

unsynced, modified-after-sync, local-only exclusion), mark_entity_synced,

mark_entities_synced batch, clear_sync_ledger_for_peer,

• Storage estimation: estimate_storage_bytes, estimate_storage_by_types
• Cloud sync cursors: save/load/upsert/clear
• Plugin fuel history: record, metrics (avg/peak/count), clear, isolation
• RAG vector index: upsert, update, delete, delete_all, cosine similarity

search, type-filtered search, get_hashes with filter, fetch_all

• Orphan management: find_orphan_entities, delete with cascade, empty

valid_types early return

• Maintenance: checkpoint, run_maintenance orphan cleanup
• DB diagnostics: returns table metadata
• Query filter edge cases: path without slash prefix, missing field,

limit break, include_trashed, bool filter, string-to-number coercion,

string-to-bool coercion

• Compact: write/delete/compact/verify data integrity
