Subject: [PATCH] Fix toggle disabled behavior via form control API

Disable the keyFiltersOperation form control when OR is not allowed.
This uses Angular's reactive form disabled state which properly
propagates through setDisabledState to tb-toggle-select, greying out
the entire toggle. If the filter had OR saved, it resets to AND and
marks the form dirty so Update is enabled. The tooltip on hover
explains why the toggle is disabled.
