Fix OAuth code exchange and go lint

Authorization-code exchange used ExternalClientID, which
is empty for registered clients and broke e2e token
grants. Pass the authenticated client's GID instead.

Also satisfy wsl_v5 blank-line rules, wire the delete
reference dialog through its mutation hook, and name the
filemanager logger.
