Replaces the two separate '+ Compare Strengths' / '+ Compare CLIP'
buttons with a single button that toggles a section showing two
labeled inputs ('Model Strengths:' and 'Clip Strengths:'). When
Strength Lock is ON, only the Model input shows (CLIP mirrors
automatically — same as today).
Also fixes button-text-not-updating bug: previously the button
required a full re-render to swap between '+ Compare Strengths' and
'✕ Array' text, so toggling the input visible left the button stuck
at '+ Compare Strengths' until page reload. Activation now persists
arrays as [1] (Python passes through unchanged) and uses array
existence rather than length>1 as the active indicator, so reloads
correctly restore the active state.
