feat(vscode): send inline review draft comments directly from diff

[marius-kilocode]

Problem

When reviewing a diff in Agent Manager (and the full-screen diff view and the vscode diff view), the inline comment composer only offered a Comment action. That action saves the draft as a pending review comment in the footer. To actually send a single line comment to the chat, you had to save it as pending first and then use the per-comment "Send to chat" icon. There was no way to send one inline draft straight to the agent in a single step.

What changed

The inline draft composer now has a Send button next to Cancel and Comment. Clicking it sends the current draft directly through the existing review-comment append path (appendReviewComments / appendReviewCommentsToTerminal with autoSend: true), the same path the saved-comment "Send to chat" icon already uses, then clears the draft without leaving a pending comment behind.

Comment keeps its existing behavior of saving a pending review comment.

Both action buttons are disabled while the textarea is empty or whitespace-only, and they now carry a proper disabled style (dimmed with a not-allowed cursor) so the unclickable state is visible rather than just functional. Cancel stays enabled.

The send dispatch was extracted into a shared sendReviewComments helper so the new draft Send button and the existing saved-comment send icon use one implementation. The change is wired into both review surfaces: the Agent Manager inline DiffPanel and the full-screen FullScreenDiffView.
