fix(android): combining inline styles

[hejsztynx]

Summary

This PR fixes two bugs regarding inline styles on Android

1. The inline code style was overwriting bold and italic inline styles, as it was switching to monochrome font, and resetting other inline styles by doing that
2. When applying an inline style with the same style present two characters later, they were incorrectly merged

Test Plan

You can walk-through the test cases in the attached videos below

Pull request overview

This PR addresses two Android-specific inline styling bugs in the enriched text input: (1) inline code styling was resetting other active inline styles (bold/italic) by forcing a normal monospace typeface, and (2) span merging logic was incorrectly considering a “next” span starting two characters later, leading to unintended merges.

Changes:

• Preserve existing bold/italic style when switching text rendering to monospace for inline code spans.
• Fix inline span merge adjacency detection by adjusting the “next span” probe range to check the immediate boundary.
