feat: consolidate ComfyUI settings and add custom words autocomplete toggle

Create unified settings.js extension to centralize all Lora Manager ComfyUI
settings registration, eliminating code duplication across multiple files.

Add new setting "Enable Custom Words Autocomplete in Prompt Nodes" (enabled
by default) to control custom words autocomplete in prompt node text widgets.
When disabled, only 'emb:' prefix triggers embeddings autocomplete.

Changes:
- Create web/comfyui/settings.js with all three settings:
  * Trigger Word Wheel Sensitivity (existing)
  * Auto path correction (existing)
  * Enable Custom Words Autocomplete in Prompt Nodes (new)
- Refactor autocomplete.js to respect the new setting
- Update trigger_word_toggle.js to import from settings.js
- Update usage_stats.js to import from settings.js
