feat(grpc): include UseOneMinuteIntervals on Site in GetRegistrationSites response

Adds bool use_one_minute_intervals = 23 to the Site message in settings.proto
and the matching UseOneMinuteIntervals property on the C# Site DTO.
Populates the new field from AssignedSite.UseOneMinuteIntervals in both
GetAvailableSites (token path) and GetAllRegistrationSitesByCurrentUser
(personal/JWT path) inside TimeSettingService, so the gRPC handler maps it
through automatically. Also fills the field in GetResignedSites for symmetry
across the three site-builders.

Mobile clients (flutter-time kiosk mode) can now select the correct
site-level minute-precision behavior at the registration step, before any
GetAssignedSite call is made.

Extends TimePlanningSettingsGrpcServiceTests
GetRegistrationSitesByCurrentUser_Success_MapsSitesToGrpcResponse to cover
both UseOneMinuteIntervals=true and =false sites and assert the field
round-trips through the gRPC mapper.
