Fix/update monitor 200 if monitor not found

[0xfurai]

Note

Update monitor now returns 404 when the target monitor does not exist, with repos propagating ErrMonitorNotFound and controller mapping it to HTTP 404.

• Backend:
  • Error handling:
    • Add ErrMonitorNotFound in modules/monitor/errs.go.
    • Map repository not-found to HTTP 404 in monitor.controller.UpdateFull using errors.Is(err, ErrMonitorNotFound).
  • Repositories:
    • Mongo: UpdateFull returns ErrMonitorNotFound when FindByID yields no result; minor import updates.
    • SQL: UpdateFull checks RowsAffected; returns ErrMonitorNotFound when 0 rows affected.
