fix(panel-v3): detección de puerto, botones y limpieza de warnings

- oasis_running() usa ss en lugar de pgrep (evita falsos positivos)
- _start_oasis() lanza oasis.sh en background y espera el puerto
- INSTALAR se deshabilita cuando OASIS ya está instalado/activo
- Corrige DeprecationWarning: override_background_color → CssProvider
- Corrige DeprecationWarning: run_javascript → evaluate_javascript
- Desactiva caché de WebKit, carga por URI directa
- Inspector de WebKit activado para depuración
