fix: missing transform properties

[AndrewShapovalov]

Summary

stringifyTransformArrayProps (introduced in #2816) is missing support for several React Native transform properties: rotateZ, rotateX, rotateY, and perspective.

When a component uses transform: [{ rotateZ: '-90deg' }], the unrecognized key falls to default case: return ''. The empty string gets joined into the transform string and passed to parse() which crashes with:

TypeError: Cannot convert null value to object

Before #2816, the old transformsArrayToProps approach copied transform entries into a flat TransformProps object and props2transform would silently ignore unknown keys via destructuring. After #2816, the string-based approach requires every key to produce valid SVG syntax and unknown keys produce empty strings that break the parser.

Changes:

In stringifyTransformArrayProps:

• rotateZ is added as fallthrough to rotate (equivalent in 2D)
• rotateX, rotateY and perspective are explicitly handled as no-ops (3D transforms with no SVG 2D equivalent)
• .filter(Boolean) is added before .join(' ') to strip empty strings from unsupported transform types

In transformToMatrix:

• Added if (stringifiedTransform) guard that prevents calling parse('') when the transform array contains only unsupported properties (e.g. [{ perspective: 500 }, { rotateX: '45deg' }])
• Wrapped parse() call in try/catch. It matches the existing error handling in the typeof transform === 'string' branch that prevents crashes from any malformed SVG transform strings

Test Plan

What's required for testing (prerequisites)?

Any React Native app using react-native-svg with a transform array containing rotateZ

What are the steps to reproduce (after prerequisites)?

• Render an SVG element with style={{ transform: [{ rotateZ: '-90deg' }] }}
• Before fix: app crashes with TypeError: Cannot convert null value to object
• After fix: rotation is correctly applied (equivalent to rotate('-90deg'))

Edge case:

• Render with style={{ transform: [{ perspective: 500 }] }}
• Before fix: app crashes with TypeError: Cannot convert null value to object
• After fix: unsupported 3D transform is silently skipped
