Subject: [PATCH] fix(translate): improve pasting and file processing (#10060)

* fix(translate): prevent default paste behavior only when handling files

Only call event.preventDefault() when handling file pasting to allow text pasting by default. This fixes the issue where text pasting was being blocked unnecessarily.

* fix(translate): append new text to existing content instead of replacing

Ensure OCR and file reading operations append new content to existing text rather than replacing it entirely. This maintains user's previous input when processing additional files.
