[Report] Add report reopen action for closed reports

- New Command_ReportReopen moderator command (extension 1206) with server
  handler that reopens resolved/dismissed reports, resets resolution state
  and notified, and records the reopening note in the audit log
- Reopen... button in the report queue action bar, gated to resolved and
  dismissed reports, with optional note prompt and tooltip
- Success confirmations for Assign, Resolve/Dismiss and Reopen now survive
  the list refresh via a pending status message instead of being clobbered
- Dispatch/auth coverage in server_moderator_role_test
