fix(handlers): log DB scan/exec errors previously silently ignored

- approvals.go Create: log parent workspace lookup Scan error
  (DB failure now surfaces instead of silently skipping escalation)
- approvals.go ListAll: log auto-expire ExecContext error
  (stale approvals no longer silently accumulate on DB failure)
- terminal.go HandleConnect: log instance_id lookup Scan error
  (workspace not found now surfaces instead of falling to local Docker silently)
- terminal.go handleLocalConnect: log workspace name lookup Scan error
  (name lookup failure now surfaces instead of being silently skipped)
