lint: fix errcheck for txn calls, query results, and unchecked errors

- Fix Rollback/Commit in compliance.go, csv/csv.go, csv/pool.go
- Capture and check errors from .One() insert queries in send.go, text.go
- Check errors from markFunc, PopulateURL, and hydrate functions
- Use lint.LogOnErrCtx for best-effort notification sends
