Pull request overview

This PR extends the Android implementation of customStyle to support fontSize and fontFamily end-to-end (JS command payload → span application → selection/state emission → HTML parse/serialize).

Changes:

• Adds fontSize and fontFamily to CustomStyle and propagates them through span state/selection and custom-style span application.
• Updates span factories and custom style span implementations to carry AssetManager + allowFontScaling so fonts and size can be applied consistently.
• Extends HTML parsing/serialization to read/write font-size and font-family within inline <span style="...">.

• parseCssFontFamily currently returns the full raw font-family value (including comma-separated stacks and partial quoting). That can’t be applied as a React Native fontFamily and also breaks round-tripping with the serializer. Consider parsing just the first family and stripping surrounding quotes/whitespace.

  private static String parseCssFontFamily(String raw) {
    if (raw == null) return null;
    String value = raw.trim();
    if ((value.startsWith("'") && value.endsWith("'"))
        || (value.startsWith("\"") && value.endsWith("\""))) {
