- sample column is always last in export and discarded on import
- get_unmapped_values now returns distinct source field values as sample instead of full raw records

- Support multi-capture-group regex: mappings.input_value changed to JSONB,
regexp_match() result stored as scalar or array JSONB in transformed column
- Computed expression fields in generated views: {fieldname} refs substituted
with (transformed->>'fieldname')::numeric for arithmetic in view columns
- Fix generate_source_view to DROP VIEW before CREATE (avoids column drop error)
- Collapsible rule cards that open directly to inline edit form
- Debounced live regex preview (extract + replace) with popout modal for 50 rows
- Records page now shows dfv.<source> view output instead of raw records
- Unified field table in Sources: single table with In view, Seq, expression columns
- Fix "Rule already exists" error when editing by passing rule.id directly to submit
- Fix Sources page clearing on F5 by watching sourceObj?.name in useEffect dep
