feat: show long branch names (#1727)
## Summary
* This change will make better use of the space available for Title and
Subtitle in the Settings (Theme: Lyra).
Instead of having a fixed maxwidth in pixels for subtitle, it will use
the whole line and shorten the longest one if needed.
So instead of: <img width="480" height="140" alt="image"
src="https://github.com/user-attachments/assets/67e4777b-10d0-4a05-b5c7-fb775776c186"
/>
It will now show: <img width="480" height="142" alt="image"
src="https://github.com/user-attachments/assets/2f143f4e-75d7-45c4-b61a-aad56bdf39fb"
/>
