- [x] I have searched the [documentation](https://docs.freetubeapp.io/) for information that matches the description of the feature request I want to file, without success.

### Problem Description

Since views are approximated anyway, the many zeroes at the end just waste space and distract. For example instead of `14,000` just show `14K` and for `3,500,000` show `3.5M`.

### Proposed Solution

Maybe add setting to enable/disable shortening

### Additional Information

_No response_

No files, tests, or entry points are named. Start by locating where view counts are rendered and where display settings are defined; the work is done when large counts use readable K, M, or B suffixes and the requested enable/disable behavior is resolved and covered consistently.
