fix: repair healthz mysql check and im tenant creation

- healthz: Scan(new(int)) is not supported by GoFrame, use .One() so
  the mysql check no longer reports a false failure
- im_tenant: set updated_by on insert for both im_tenant and
  im_tenant_config, otherwise new tenant creation fails with
  "Field 'updated_by' doesn't have a default value"
- gitignore: exclude .trae/ local debugging artifacts
