Channel selector dropdown truncates long version/date strings

Bug Description

When a snap has a version number or last-updated date with a long string, the channel picker dropdown does not display the full information — the text gets cut off with ellipsis (...) and the layout appears broken.

Steps to reproduce the behavior

1. Open Ubuntu App Center
2. Search for a snap that has multiple channels available (e.g. OBS Studio by Snapcrafters, or Thunderbird)
3. Click the channel selector dropdown next to the "Open" button

Expected behavior

All channel information (Canal, Versión, Última actualización) should be fully visible, or at minimum the channel name (e.g. stable, beta, candidate) — the most critical piece of information — must always be fully readable. The dropdown should resize to accommodate longer strings if needed.
