feat: misc additions

- Detect extensions that didn't update between updates
- Add composer why not command where approriate (when extension didn't update, when major update failed)
- Detect incompatible extensions in major update failure and show the extensions in the frontend
- Create last update run setting value which holds the state of the latest update runs
- Other fixes
