Ensure new Agent apps (AppMode.AGENT) can access all workflow-related
APIs and Service API chat endpoints:
- Add AppMode.AGENT to 13 workflow controller mode checks
- Add AppMode.AGENT to 4 workflow_run controller mode checks
- Add AppMode.AGENT to workflow_draft_variable controller
- Add AppMode.AGENT to Service API chat, conversation, message endpoints
- Add AgentV2Node.get_default_config() with prompt templates and strategy defaults
- 46 unit tests all passing (8 new Phase 7 tests)
Old agent/agent-chat paths remain completely unchanged.
