Add Pano Scrobbler repository

**Is your feature request related to a problem? Please describe.**
Currently, Droid-ify does not include the repository for Pano Scrobbler, a popular app for scrobbling music plays to Last.fm and other services. Users who rely on Droid-ify as their primary F-Droid client must manually add the Pano Scrobbler repository to access the app, which can be inconvenient and less user-friendly.

**Describe the solution you'd like**
I would like Droid-ify to include the Pano Scrobbler repository by default. The repository URL is:
[https://kawaiidango.github.io/pano-scrobbler/fdroid/repo/](https://kawaiidango.github.io/pano-scrobbler/fdroid/repo/)
Fingerprint: `9954ECAB27F9FCE8290AC75A33F3DFE9FE5F6F5B8E6F33AD7F98307AC4D487BA`

This would allow users to easily discover and install Pano Scrobbler directly through Droid-ify without needing to manually add the repository.

**Describe alternatives you've considered**
Manually adding the repository to Droid-ify, which works but is not ideal for new or just lazy users.

**Additional context**
Pano Scrobbler is a widely used app for music scrobbling, and its repository is trusted and well-maintained.
