feat: Add service CRUD to the catalog provider

[mashawes]

Extends the catalog with service CRUD, following the same pattern as region (#723).

• Adds ServiceCreate and ServiceUpdate types in core-types with validator length limits (id max 64, type and name max 255) and alphabetized fields.
• Adds create, update, and delete to the catalog-sql driver. Read, list, and get already existed. A service's name is stored inside the extra JSON blob so create and update merge it there.
• Wires the new methods through the CatalogApi provider including provider_api, service, mock, and mod, calling validate() early in create, update, and list.
• Adds integration tests under tests/integration/src/catalog/service/ covering create, get, list with type filter, update, and delete, plus not-found and over-length validation cases.

Closes #724

in the database model we have only id/enabled/type/extra. All other fields are captured as json under extra. As such we should not try to re-expose the "name" here separately since it is anyway an optional field. Please remove "name" field from models
