Motivation

• The handwritten services.custom.ts duplicated endpoints/types already present in the generated client, creating maintenance burden and drift.

Description

• Delete the redundant frontend/src/client/services.custom.ts file and switch consumers to the autogenerated client surface from @/client.
• Replace adminDeleteOrganizationWithConfirmation with the generated adminDeleteOrganization (which accepts confirm) in frontend/src/hooks/use-admin.ts.
• Replace usages of CustomOAuthProviderCreateRequest with the generated CustomOAuthProviderCreate type and import providersCreateCustomProvider, triggersCreateCaseTrigger, and triggersGetCaseTrigger from @/client in frontend/src/lib/hooks.tsx.
• Update imports and call sites in use-admin and shared hooks to consume generated types/functions instead of the deleted custom module.

Testing

• Ran pnpm -C frontend check (Biome/format+lint) which completed and fixed one file successfully.
• Ran pnpm -C frontend run typecheck (TypeScript tsc --noEmit) which completed successfully with no type errors.
