Fix sidebar project removal

Remove projects through a daemon RPC so the sidebar can delete the project
record after archiving its active workspaces. Reopening a removed directory
recreates the missing project record so local projects keep their derived
basename, and History skips orphaned archived workspace rows.

Fixes #1583.
