feat(server): support for read-only assets and importing existing items in the filesystem (#2715)

* Added read-only flag for assets, endpoint to trigger file import vs upload

* updated fixtures with new property

* if upload is 'read-only', ensure there is no existing asset at the designated originalPath

* added test for file import as well as detecting existing image at read-only destination location

* Added storage service test for a case where it should not move read-only assets

* upload doesn't need the read-only flag available, just importing

* default isReadOnly on import endpoint to true

* formatting fixes

* create-asset dto needs isReadOnly, so set it to false by default on create, updated api generation
