fix(ios): align inline views with inherited fonts and line heights

[mym0404]

Summary:

iOS Fabric inline <View> attachments use a fallback font and miss the baseline offset from an explicit lineHeight. Preserve the enclosing <Text> font on each attachment and subtract NSBaselineOffsetAttributeName when positioning the View.

[IOS] [FIXED] - Align inline Views with inherited fonts and explicit lineHeight.

Test Plan:

• RNTester source builds and agent-device on iPhone 17 Pro / iOS 26.5, at font scales 1.0 and 2.143: all nine measurable samples are within one physical pixel (1/3 pt). lineHeight: 48 public error is 10.293 pt before and -0.041 pt after; native baseline error is 0 pt after.
• Existing RCTAttributedTextUtilsTest and RCTFontTests: 35 passed, 0 failed. clang-format, ESLint, Prettier, and git diff --check passed. Commands and test results are in the measurements above.
• Android API 37 comparison: nine samples within 0.0001 dp at font scales 1.0 and 1.75 (results). Android renderer code is unchanged.

Nested Text returns a zero-size public View frame and is excluded from numerical comparisons.
