feat(remote): Enhance remote branch management and stability

Improved handling for deleting remote branches across the application, enhancing both user experience and backend reliability. This includes adding structured logging to all Git remote operations in Rust, refining UI components to handle remote-specific deletion flows, and providing clear status/error feedback in sync settings.

- Standardized styling for action toggles (Stash, Branch, Explorer) using consistent dimensions.
- Implemented detailed console logging for all Git remote operations on the backend.
- Refined dialogs and sync settings to provide explicit status and error messages during remote management.
