feat: Add option to disable CloudProviders sidebar integration

Adds a new setting in General preferences to control whether synchronized folders appear in the file manager sidebar via CloudProviders on Linux.

Changes:
- Add 'showCloudProvidersInFileManager' config setting (defaults to true)
- Add checkbox in General Settings UI (Linux only)
- Check setting during CloudProviderManager initialization
- Skip DBus registration when disabled

The setting requires application restart to take effect.
