feat: add edit support for env vars, labels, and volumes

- Add POST /apps/{id}/env-vars/{varID}/edit endpoint
- Add POST /apps/{id}/labels/{labelID}/edit endpoint
- Add POST /apps/{id}/volumes/{volumeID}/edit endpoint
- Add inline edit UI with Alpine.js toggle in app_detail template
- Models already support Save() with update when ID != 0

Closes #67
