test(mcp-server): add 8 ChronoMind MCP tool registration + schema tests

- Verify all 15 tools registered (timers, routines, sync, planner, agent-actions)
- Check admin role requirement on every tool
- Validate input schemas for key tools (planDay, planNl, reschedule, availability)
- Resolves TODO-007 from ChronoMind roadmap
