[FEATURE] Allow users to deactivate Remote Control session links after shutdown

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When a Remote Control session is shut down (via Ctrl+C or closing the terminal), the session link remains accessible even though the session is no longer active. While the session is effectively non-functional, the link still loads, which is confusing and a potential security concern. It is unclear how long the link remains accessible, and there is no way for users to manually invalidate it.

Proposed Solution

Expected Behavior
Users should be able to deactivate/delete a Remote Control session link after the session has been shut down.

Feature Request

1. List past session links — A CLI command like claude remote-control --list to show recent session links and their status.
2. Revoke shut-down session links — A CLI command like claude remote-control --revoke <session-id> to deactivate links from sessions that are no longer running.
3. Deactivate from the web UI — A button on the Remote Control web page to deactivate the link when the session is no longer active.

Why This Matters

• Security: Shut-down session links should not remain accessible with no way to clean them up. Users should have control over invalidating stale links.
• Shared environments: On shared machines, stale session links could be discovered by others.
• UX: It's confusing when a shut-down session's link still loads, with no option to remove it.
