disabling enter keyboard when approve/reject pending (#1776)

<!-- This is an auto-generated description by cubic. -->
## Summary by cubic
Disable Enter-to-send when approve/reject is pending to prevent
accidental message submission. Enter now respects the disableSendButton
state; Shift+Enter still adds a newline.

- **Bug Fixes**
  - Pass disableSendButton from ChatInput to LexicalChatInput.
- Update EnterKeyPlugin to ignore Enter when disableSendButton is true,
while keeping Shift+Enter for newline.

Summary will update automatically on new commits.</sup>
