**Title:** CodeRepo repository and service layers

**Status:** pending

**Dependencies:** 119

**Priority:** medium

**Description:** Create CodeRepoRepository and CodeRepoService with credential resolution through SecretService

**Details:**

Create src/mcpd/src/repositories/code-repo.repository.ts and src/mcpd/src/services/code-repo.service.ts:
1. Repository: standard CRUD, findByProjectId
2. Service.create(): validate project exists, validate credSecretId/Key if provided
3. Service.resolveCredentials(repoId): fetch Secret via SecretService, extract the key, return credential (never store plaintext)
4. Service.update(): validate changes
5. Service.delete(): check no active sessions reference this repo
6. Follow existing service patterns for validation

**Test Strategy:**

Unit tests: test create with valid project, test credential resolution returns correct value, test create fails with invalid secret reference, test findByProjectId returns filtered list.
