feat(web): add command palette fuzzy search

[gitmotion]

Hey there! awesome repo, just hopped on opencode and stumbled across this 🙌🏻

Noticed there was a search models functionality and thought it could use some enhancements by adding a command palette with search, actions, grouping, etc to help with navigating through the list of models and providers

Previews:

Description	Preview
Models, Providers, Sort (Grouping & Search by model in parent/child directories)
Mobile Friendly - Tap/Click & Responsive - Fixed Search Icon Alignment in later commit
Models.dev Section (Github External link & How to Use)
Light & Dark Mode (Works with current theme handling)
