Perspective table is now created with index: 'pf_id'. Delete endpoints
return the pf_ids they removed; the client calls table.remove(pf_ids)
in undoEntry. Avoids the full /data refetch that dominated undo time.

- Sources page: left column with stacked DB tables + registered sources panels,
right column as full-height column mapping workbench
- Add compact table search, column search, table preview button, delete source button
- Rename fc_table system columns to pf_ prefix (pf_id, pf_iter, pf_logid,
pf_created_at) to avoid collisions with source table columns like 'id'
- Remove 'filter' col_meta role — any non-ignore column usable in baseline filters
- Replace structured filter row builder with free-form SQL WHERE clause textarea
and clickable column chips for insertion; fully flexible AND/OR logic
- Baseline segment cards now display raw WHERE clause text + offset
