380 rest endpoints go fast time server closes #380 (#701)

* feat: Implement REST endpoints for fast-time-server (#380)

- Added new 'rest' transport mode for REST API only access
- Enhanced 'dual' mode to include both MCP and REST endpoints
- Implemented comprehensive REST API endpoints:
  * GET /api/v1/time - Get current time in any timezone
  * POST /api/v1/convert - Convert time between timezones
  * POST /api/v1/convert/batch - Batch time conversions
  * GET /api/v1/timezones - List available timezones with filtering
  * GET /api/v1/timezones/{tz}/info - Get timezone details
  * Test endpoints for debugging and performance testing
- Added OpenAPI 3.0 specification and Swagger UI documentation
- Implemented CORS support for browser-based testing
- Added comprehensive test coverage for all REST endpoints
- Updated README with REST API documentation and examples

The REST endpoints complement the existing MCP protocol support,
making it easier to test and integrate the fast-time-server with
traditional REST tooling and the MCP Gateway REST adapter.

 ## Project Overview
 
 MCP Gateway (ContextForge) is a production-grade gateway, proxy, and registry for Model Context Protocol (MCP) servers. It federates MCP and REST services, providing unified discovery, auth, rate-limiting, observability, virtual servers, multi-transport protocols, and an optional Admin UI.
