refactor(ui): Improve title bar layout using flex and grid

The structure of the application title bar has been updated to utilize modern CSS layout techniques like Grid and Flexbox. This refactoring improves the responsiveness and organization of key elements such as repository name, branch indicator, and synchronization status. The changes ensure better alignment and handling of varying content lengths across different viewports.

- Restructures repo/branch info into a dedicated context container
- Uses flex properties for dynamic sizing of title bar sections
- Groups sync indicators into a cohesive unit
