* chore: correct filename typo

* chore: change disabled icon

* chore: revert accidental defsettings changes

* format

* add timeout to frontend importPlugin

if a request hangs this prevent it from blocking other plugin loads.
backend diaptch_plugin which calls this for individual plugin load (as opposed to batch) is set to 15s.
other callers of importPlugin are not using timeout, same as before.

* fix plugin update checking loop
