john-okeefe 3b3630666a docs: integrate API explorer into documentation pages
Phase 3 complete: Add API explorer to endpoint documentation
- Add DocsLayoutWithExplorer template function
- Update HTTPHandler.ShowAPIEndpoint to check authentication
- Add GetAPIEndpointData method to docs handler
- Include API explorer for all endpoint documentation
- Explorer shows mock data to non-authenticated users
- Explorer enables real API execution for logged-in users
- Add legacy fallback for endpoints without explorer data
