feat: Add configurable LoRA strength adjustment step setting

Implements issue #808 - Allow users to customize the strength
variation range for LoRA widget arrow buttons.

Changes:
- Add 'Strength Adjustment Step' setting (0.01-0.1) in settings.js
- Replace hardcoded 0.05 increments with configurable step value
- Apply to both LoRA strength and CLIP strength controls

Fixes #808
