[Bug]: restore text paste in the iOS chat composer

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/mobile

Steps to reproduce

1. Open T3 Code mobile on an iPhone and open a chat.
2. Focus the chat composer.
3. Switch to another app or tab containing text. The recording uses Docs.
4. Select and copy some text.
5. Switch back to T3 Code.
6. Long-press inside the chat composer to open the native edit menu.
7. Try to paste the copied text.
8. Notice that nothing appears and nothing pastes

Expected behavior

Paste should remain available and insert the copied text at the cursor while preserving the existing draft.

Actual behavior

After switching back to T3 Code, the native edit menu does not show Paste, or Paste does not insert anything. The existing draft remains unchanged, even though the clipboard still contains text.

Impact

Major degradation or frequent failure

Version or commit

Version 1.0.1 of iPhone App

Environment

Workaround

No reliable workaround identified.

Start in apps/mobile by reproducing the issue on an iPhone with a chat draft, switching to another app such as Google Docs, and attempting to paste from the native edit menu. Investigate the mobile chat composer’s text-input behavior; done means copied text can be pasted at the cursor after returning to T3 Code while preserving the existing draft.
