Update MCP deployment guide for HTTP transport (#853)

* Update MCP deployment guide for HTTP transport migration

- Update architecture diagram from HTTP/SSE to HTTP
- Update server transport from sse to streamable-http
- Update Claude Code client config from transport:sse to type:http
- Update Python client examples to use streamable_http_client
- Update all /sse endpoints to /mcp
- Update server configuration examples with new host/port API
- Update curl testing commands

This completes the documentation updates for the HTTP transport migration
started in PR #852.

* Update dashboard deployment guide for HTTP transport migration

- Update all MCP server URLs from /sse to /mcp endpoint
- Update environment variable examples
- Update systemd service configuration examples
- Update troubleshooting curl commands

This ensures dashboard deployment documentation is consistent with the
MCP server HTTP transport migration.
