Reuse `TypeScript` types with five utility types

Small type transformations cover many form, list, and API DTO cases. Partial, Pick, and Omit reduce duplicate model types; useful for keeping small codebases tidy.

[ KEY POINTS ]
  1. Partial fits edit forms where every field can be optional; it avoids maintaining a separate patch type by hand.
  2. Pick and Omit create list or public-view types from an existing model. Less duplication means fewer schema drift bugs.
  3. Record is useful for maps keyed by known strings, such as status labels or role-based UI config.
