refactor(ui): simplify branch status display and adjust layout

The changes simplify how branch status is shown in HistoryPanel.
The remoteName helper and the check icon were removed.
Status is composed inline with the label for local and remote branches.
CSS tweaks wrap content and adjust widths for better responsiveness.

- Remove remoteName helper and Check icon from HistoryPanel
- Inline status text for local/remote branches and avoid icons
- Improve graph layout: wrap refs and constrain widths on hover
