Purge cached docs and remove docs from all workspaces on vectorDB/embedder changes (#2819)

* wip remove all docs clear vector db on embedder/vector db change

* purge all cached docs and remove docs from workspaces on vectordb/embedder change

* lint

* remove unneeded console log

* remove reset vector stores endpoint and move to server side updateENV with postUpdate check

* reset embed module

* remove unused import

* simplify deletion process
rescoped document deletion to be more general for speed, everything needs to be reset anyway
fixed issue where unembedded docs not in any workspaces, but cached, were not removed

* add back missing readme file
update warning text modals
