fix(identity): resolve tenant child-data seeding failures and branding panel enum mismatches

- Fix FindBranch/FindIdentityProvider in Tenant.cs to compare Props.Id instead of
  entity.Id (random GUID from Entity base constructor); this made ActivateIdentityProvider
  always return NotFound, leaving a lingering BrokenRule that silently aborted SetBranding
- Add DomainEvents.MarkChangesAsCommitted() to InMemoryUserManagementDelegationRepository.Seed()
- Replace monolithic DevDataSeeder with per-bounded-context seeders (Identity, Authorization,
  Approvals, Configuration, IGA, Audit) orchestrated by CoreDevDataSeeder
- Fix BrandingPanel select values to match DomainEnumerationParser.FromName<> expectations:
  backgroundStyle SolidColor/Gradient/Image, logoFormat Png/Svg
- Add brandBgImage i18n key (ES/EN) for Image background style option
- Update MSW mock handlers and add mock data fixtures for tenants, user accounts, delegations
