refactor(mcp): address review — split files, fix naming, stateless router

Split the monolithic mcp.router.ts into focused modules:
- mcp.service.ts: coordination helpers (rundownListResponse, renameRundown, deleteRundown)
- mcp.tools.ts: tool definitions (ontime_ prefix, annotation presets, shared field schemas,
  CHARACTER_LIMIT truncation) + handleToolCall dispatcher
- mcp.prompts.ts: prompt definitions + handleGetPrompt
- mcp.resources.ts: resource definitions (schema, live data, docs) + handleReadResource
- mcp.server.ts: createMcpServer factory that wires the above modules
- mcp.router.ts: thin stateless Express router (POST/GET405/DELETE405)

Other changes per review comments:
- Rename ontime_delete_event → ontime_delete_entry (entry vs event naming convention)
- Remove hardcoded cue/colour prefix conventions from tool descriptions and prompts;
  replace with "ask the user what convention they prefer"
- Remove automations tools (left for a later PR)
- Add Bearer auth comment in authenticate.ts explaining the MCP use case
- Extract McpSection component from FeaturePanel to isolate URL state re-renders
- Update bulk_edit prompt to mention linkStart cascade behaviour
- Add 405 comments explaining why GET/DELETE are not supported in stateless mode
