Ensure all file volume paths are validated and properly escaped before
use. Previously, only directory mount paths were validated at the input
layer — file mount paths now receive the same treatment across Livewire
components, API controllers, and the model layer.
- Validate and escape fs_path at the top of saveStorageOnServer() before
any commands are built
- Add path validation to submitFileStorage() in Storage Livewire component
- Add path validation to file mount creation in Applications, Services,
and Databases API controllers
- Add regression tests for path validation coverage
