Bug: Repository page truncates repo name when owner login is long #154

Summary

On the repositories page, long owner names consume most of the available width and the repository name becomes barely visible.

Example: a-long-user-name/a-repository renders in a way where the repo segment is hard to read.

Steps to Reproduce

1. Open the repositories page.
2. Find a repo where the owner login is long.
3. Observe the owner/repo display label.

Actual Behavior

The owner part takes most of the space and the repo name is heavily truncated or barely visible.

Expected Behavior

The repo name should remain clearly readable even when the owner name is long (for example by truncating owner first, balancing truncation, or prioritizing repo segment visibility).

Impact

Makes it harder to identify repos at a glance on the repositories page.
