refactor: rename cmds module to cmd for better consistency (#2830)

- Renamed `cmds` module to `cmd` for better naming consistency
- Reorganized command modules into separate files under src/cmd/
- Updated all imports and references to use the new module name
- Fixed missing dependency in webdav.rs to reference core::backup
- Updated tray module to use new cmd namespace
- Improved uwp.rs module structure using platform-specific implementations
- Removed unnecessary imports from various command files
