- Run button executes edited SQL directly via new exec-sql endpoint
- generate_stack_view gains p_dry_run mode for preview without executing
- CASCADE drop detects dependent stacks, marks them stale in DB and status bar
- net_balance moved to last column in generated view
- Backfill 458 missing dcard rows and 123 missing chase rows from TPS migration bug
