fix: update Xdebug config to Xdebug 3 format across dev images

- Add xdebug.client_port=9003 (Xdebug 3 default, was implicit)
- Change start_with_request: yes -> trigger (explicit activation required)
- Add develop mode alongside debug (enables var_dump improvements etc.)
- Increase max_nesting_level: 250 -> 512
