PR Title Suggestion: `fix: Preserve line breaks on multi-line paste in mobile WebViews`

Changelog Entry

Description

This PR fixes a bug where pasting multi-line text from clipboard suggestions on mobile WebViews (e.g., Android in-app browsers) would strip line breaks, collapsing all content onto a single line. The fix detects these specific environments and manually reconstructs the pasted content with the correct line breaks (hardBreak nodes) using a ProseMirror Fragment, ensuring formatting is preserved without affecting other paste scenarios.

Added

Logic to detect mobile WebView environments based on User-Agent strings.
A custom paste handler that activates only for multi-line text within a mobile WebView.

Changed

The paste event handler in the rich text input component now manually creates a ProseMirror Fragment to preserve newlines in the specific problematic environments.

Breaking Changes

N/A

Additional Information

This is a targeted workaround for a known issue in how certain WebViews handle clipboardData from suggestion-based paste actions (e.g., Gboard's clipboard history).
The solution uses Fragment.fromArray() and a replaceWith transaction for a robust and efficient insertion, as per ProseMirror best practices.
Fixes #15053.
