feat: implement POST /api/v1/agents/<agent_id>/upload API (#15633)

## Summary Implement the `POST /api/v1/agents/<agent_id>/upload` endpoint in Go, allowing file uploads associated with agent canvases. ### Changes - **Modified**: `internal/service/agent.go` — Added `CheckCanvasAccess` method (owner + team-level permission semantics) - **Modified**: `internal/handler/agent.go` — Added `UploadAgentFile` handler with auth check, multipart file parsing, and delegation to `FileService`. Added `fileUploader` interface for testability. - **Modified**: `internal/router/router.go` — Registered `POST /:agent_id/upload` route - **Modified**: `cmd/server_main.go` — Wired `fileService` into `AgentHandler` - **New**: `internal/service/agent_test.go` — 4 service-level tests for `CheckCanvasAccess` (owner, team member, private denial, not found) - **New**: `internal/handler/agent_upload_test.go` — 3 handler-level tests (success with fake file service, cross-user denial, empty file rejection) ### Testing All 7 tests pass with zero mocking of the DB layer (in-memory SQLite): ``` === RUN TestCheckCanvasAccess_Owner --- PASS === RUN TestCheckCanvasAccess_NotOwner --- PASS === RUN TestCheckCanvasAccess_PrivateCanvas_Denied --- PASS === RUN TestCheckCanvasAccess_NotFound --- PASS === RUN TestUploadAgentFileHandler_Success --- PASS === RUN TestUploadAgentFileHandler_NoPermission --- PASS === RUN TestUploadAgentFileHandler_NoFiles --- PASS ``` Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
