feat(loras): warn when widget strength leaves the usage-tips range

The cycler-list payload now carries usage_tips, and the LORAS widget
parses strength_min/strength_max/strength_range into a cached lookup.
Strength inputs (model and clip) turn amber with an explanatory tooltip
when dragged, typed, or stepped outside the recommended range.
