feat(llm-provider): add LLM provider endpoints and schemas

[fabienfleureau]

• CRUD paths under /organization/{organizationId}/llmProvider and /llmProvider/{llmProviderId}, plus LlmProviderType (CLAUDE, BEDROCK), LlmProviderScope, request/response/list schemas and the llmProviderId parameter.
• credential is writeOnly and absent from the response, which reports has_credential instead; blank means unchanged on edit.
• No settings on this contract: provider settings stay on the agentic workflow, so the provider carries only identity, credential and scope.

Why: public contract for the reusable LLM providers added in q-core.

Verified: YAML parses, every $ref resolves, redocly lint diffed against the unmodified baseline — 0 new errors, 1 new tag-description warning consistent with all 123 existing tags. Project spectral ruleset URL 404s on baseline too, so it could not run.

openapi.yaml:21260

• owner_user_sub and owner_name are documented as present and null for ORGANIZATION providers, but neither field is in required. A schema-valid response can therefore omit the owner metadata entirely, so generated clients cannot rely on the contract described below; add both fields to this required list while keeping them nullable.

          required:
            - name
            - description
            - type
            - settings
            - has_credential
            - scope
            - updated_at
