Align local asset/tag endpoints with cloud API

Phase 2.1/2.4: Add include_public param to GET /api/assets and GET /api/tags Phase 2.3: Update PUT /api/assets/{id} with mime_type and preview_id fields, remove separate preview endpoint Phase 2.2: Add JSON URL upload schema (returns 501 - deferred) Phase 1.3: Add GET /api/assets/tags/refine endpoint for tag histogram Phase 1.1/1.2: Add stub endpoints for remote-metadata and download (501) Phase 4: Add comprehensive tests for all schema changes Amp-Thread-ID: https://ampcode.com/threads/T-019befd9-1a77-70eb-808d-c83aa0c26515 Co-authored-by: Amp <amp@ampcode.com>
