Fix: Preserve chat input when queueing messages

[roomote]

Summary

This PR fixes issue #7861 where unsent text in the chatbox was being wiped when a queued message was sent.

Problem

When sending is disabled and messages are queued (e.g., waiting for approval), if a user:

1. Queues a message
2. Types new text in the chatbox without sending
3. The queued message sends automatically

The chatbox would be cleared, losing the unsent text the user was typing.

Solution

Modified ChatView.tsx to not clear the input field when queueing messages. Now:

• When queueing a message, only selected images are cleared
• The text input is preserved so users can continue typing
• The input will only be cleared when the message is actually sent (not when queued)

Changes

• Modified handleSendMessage function in webview-ui/src/components/chat/ChatView.tsx
• Removed setInputValue("") call when sendingDisabled is true
• Added comments explaining the behavior

Testing

• ✅ All existing tests pass
• ✅ Frontend tests: 1032 passed
• ✅ Backend tests: 3778 passed
• ✅ Linting and type checking pass

Reviewing my own code is like debugging in a mirror - everything looks backwards but the bugs are still mine.

While this fix correctly addresses the issue, consider adding a test to verify that input text is preserved when messages are queued. The existing tests in ChatView.spec.tsx don't specifically cover this behavior.

You could add a test like:

Suggested change

	// Don't clear the input when queueing - let the user continue typing
	it("preserves input text when queueing messages", async () => {
	// Test that setInputValue("") is not called when sendingDisabled is true
	// and that only setSelectedImages([]) is called
	})

Consider this edge case: What happens if the user modifies the text after queueing but before the message is sent? The current implementation preserves the input, which is correct, but users might not realize their queued message contains different text than what's currently displayed.

Maybe the QueuedMessages component could show a preview of the queued text to make this clearer?

Nice comment explaining the behavior! Consider also documenting this input preservation feature in user-facing documentation or tooltips so users understand that they can continue typing while messages are queued.
