Set TypeScript to strict mode and fix issues related to server types (#261)

* Fix lint issues and some other TS issues

- set TypeScript in strict mode
- add npm commands to lint / check code
- fix all lint issues
- fix some TS issues
- rename User reponse DTO to make it consistent with the other ones
- override Express/User interface to use UserResponseDto interface
 This is for when the accessing the `user` from a Express Request,
 like in `asset-upload-config`

* Fix the rest of TS issues

- fix all the remaining TypeScript errors
- add missing `@types/mapbox__mapbox-sdk` package

* Move global.d.ts to server `src` folder

* Update AssetReponseDto duration type

This is now of type `string` that defaults to '0:00:00.00000' if not set
which is what the mobile app currently expects

* Set context when logging error in asset.service

Use `ServeFile` as the context for logging an error when
asset.resizePath is not set

* Fix wrong AppController merge conflict resolution

`redirectToWebpage` was removed in main as is no longer used.
