feat(openmetadata): profiler + data-quality tests for data insight

Profiler:
- pg/mysql: table-level metrics via DB statistics (exact-ish row counts) only;
  source tables hold 24-53M rows and OM's column profiler full-scans per column
  (no TABLESAMPLE pushdown), which would hammer the live CDC source.
- trino/iceberg: full column metrics + sample data on the small (20-25k row)
  curated_masked + hadoop tables.

Data quality: 16 test cases across 5 tables (row counts on big sources; row
count + uniqueness/not-null/range on curated/masked + historical), all passing.
This populates OM's Data Quality dashboard (coverage, healthy assets,
dimensions, test results).
