refactor: Update Neogit configuration preferences

- Change graph style from ASCII to Kitty for better visual representation
- Enable commit signature verification (verify_commit = true)
- Remove Telescope dependency, use Snacks.nvim picker exclusively
- Remove GitLab from git services, keep only GitHub

Streamlined configuration with fewer dependencies while maintaining
full functionality through Snacks.nvim integration.
