## Summary
Replace MDI font icons with Tailwind Iconify (Lucide) icons for Settings
and Manage Extensions menu items to fix size inconsistency with Browse
Template icon.
## Changes
- **What**: MDI font icons (`mdi mdi-cog-outline`, `mdi
mdi-puzzle-outline`) rendered at 14px (`text-sm` font-size), while the
Tailwind Iconify icon (`icon-[comfy--template]`) rendered at ~16.8px due
to `scale: 1.2` in the Tailwind plugin config. Replaced with
`icon-[lucide--settings]` and `icon-[lucide--puzzle]` so all icons use
the same rendering pipeline.
