🧹 Remove FontAwesome SVG assets from git — use webfonts instead

[fusion94]

Description

The assets/svgs/ directory contains thousands of individual SVG files from FontAwesome Pro. These are not referenced by the site (which uses the CSS/webfont approach) and bloat the repo significantly.

Impact

• Massive repo size increase
• Slow clones
• Noise in git history

Fix

1. Verify no SVG files are directly referenced in any HTML/CSS
2. Remove assets/svgs/ directory
3. Add assets/svgs/ to .gitignore to prevent re-adding

Acceptance Criteria

• assets/svgs/ removed from repo
• No broken icon references
• .gitignore updated
