Fix git configuration for OpenHands Cloud environments

- Add environment variables as fallback for git user configuration
- Implement fallback strategy: try global config first, then local config file
- Add verification commands to ensure git config is applied
- Enhance error handling and logging for git configuration commands
- Add debug endpoint /debug/git-config for troubleshooting
- Improve test coverage for git configuration scenarios

Fixes issue where git user.name and user.email were not being set
properly in cloud/containerized environments due to permission issues
with global git configuration.
