CyberMind-FR 7a3b3eca23 fix(haproxy): Parse inline servers and enable port editing
- RPCD _add_backend now parses inline 'server' option format
- Servers embedded in backend response with inline flag
- update_server converts inline servers to separate UCI sections
- delete_server handles both inline and separate server sections
- API and UI pass inline flag for proper handling

Fixes server port editing in LuCI backends interface.
