Implement records API methods (list, search, get, versions)

[ran-codes]

Description

Implement the API-layer methods for records endpoints.

Requirements

• FR-2.1: GET /api/user/records — list user's records and drafts
• FR-2.2: GET /records/ — search published records with Elasticsearch query
• FR-2.3: GET /records/:id — get full record details
• FR-2.4: GET /api/records/:id/versions — list all versions

Acceptance Criteria

• internal/api/records.go with methods:
  • ListUserRecords(params) — paginated, supports --status and --community filters
  • SearchRecords(query, params) — paginated, supports --community filter
  • GetRecord(id) — single record fetch
  • ListVersions(id) — paginated version list
• All methods return typed model structs
• Pagination support (page/size params, link header parsing)
• Unit tests with httptest mock server
