refactor: consolidate MCP server configuration properties into unified structure

Replace 4 separate configuration classes with unified McpServerProperties:

- Consolidate all MCP server config under spring.ai.mcp.server prefix
- Add nested classes for protocol-specific settings (SSE, Streamable, Stateless)
- Update configuration paths and test cases accordingly
- Follow Spring Boot ServerProperties pattern

This eliminates configuration fragmentation and provides single entry point for users.
