Marcel c90b42d045 feat(documents): add density and date-range repository queries (#385)
Native SQL aggregations backing GET /api/documents/density:
- findDensityByMonth groups documents by truncated meta_date with optional
  from/to bounds (frontend fills zero-count gaps).
- findMinMaxDocumentDate returns the earliest/latest meta_date via projection,
  null on empty archive.

Covered by DocumentDensityIntegrationTest (Testcontainers PostgreSQL): empty
archive, single+multi-month grouping, from/to bounds, null meta_date exclusion,
min/max edge cases.
