initial download-folder-selector interface (#890)

* initial download-folder-selector interface

* use primevue select

* add a folder select visibility checkbox

* slightly reduce indirection

* fix up select box updating

* revert bad upstream changes

* cleanup

* allow localhost sourced models in ui side

(for testing purposes only basically, but does no harm in deployed envs)

* add screenshot expectations to test

* Update test expectations [skip ci]

* add testing of folder select

* fix test

* don't exclude folder selector when there's only 1

since the checkbox covers that better anyway

* oo - fix checkbox

* Update test expectations [skip ci]

* testing - don't expect screenshots :(

* experimental new test code

* toHaveClass is silly

* add // comments documenting intent of allowedSources
