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

* updated code to reflect changes in MR

* fixed read stream promise return type

* new index for originalPath, check for existing path on import, reglardless of user, to prevent duplicates

* refactor: import asset

* chore: open api

* chore: tests

* Added externalPath support for individual users, updated UI to allow this to be set by admin

* added missing var for externalPath in ui

* chore: open api

* fix: compilation issues

* fix: server test

* built api, fixed user-response dto to include externalPath

* reverted accidental commit

* bad commit of duplicate externalPath in user response  dto

* fixed tests to include externalPath on expected result

* fix: unit tests

* centralized supported filetypes, perform file type checking of asset and sidecar during file import process

* centralized supported filetype check method to keep regex DRY

* fixed typo

* combined migrations into one

* update api

* Removed externalPath from shared-link code, added column to admin user page whether external paths / import is enabled or not

* update mimetype

* Fixed detect correct mimetype

* revert asset-upload config

* reverted domain.constant

* refactor

* fix mime-type issue

* fix format
