Bug description

After a required manual upgrade of my NextCloud instance, I discovered that several files were reported as missing - probably due to an incomplete upload. While this was easy to fix, I noticed that not all missing files are reported with their exact location (path + filename) which made it more difficult than necessary to track down the missing files and re-upload them. Example report:

For instance, the first entry should actually be reported as apps/twofactor_totp/js/main-login-setup.js.map.license - which is the file that's missing.

I noticed that some other files (not in the /apps/ directory) were reported with the correct path, but I propose to align this across all files to make it easier to fix.

Steps to reproduce

1. Install NextCloud
2. Delete some files in any of the apps/xyz/js directories
3. Run the integrity scanner
4. View the resulting report

Expected behavior

I would like the correct path to be shown in clear text.

Additional info

No response

Start at the integrity scanner and the code that formats its missing-file report; the issue provides a reproducible case by deleting files under an apps/xyz/js directory and running the scanner. Done means missing app files are displayed with their full apps/... path, while non-app paths remain correct.
