Fix custom fonts not displaying in WKWebView by replacing CSS `src: local()`
with `src: url()` using bundle file paths. WKWebView cannot resolve fonts via
local() even when registered in Info.plist UIAppFonts.
Changes:
- Add fontFileNames and cssFontFamily properties to FontFamily enum
- Implement generateFontFaceCSS() helper in WebView.swift and NativeWebView.swift
- Generate @font-face CSS with file:// URLs for all 12 font files
- Fonts are now dynamically loaded from FontFamily enum (single source of truth)
Affected fonts:
- Literata (Regular, Bold)
- Merriweather (Regular, Bold)
- Source Serif 4 (Regular, Bold)
- Lato (Regular, Bold)
- Montserrat (Regular, Bold)
- Source Sans 3 (Regular, Bold)
