Fix terminal size query in handle_enter for test environments

The CI tests were failing because handle_enter() was using
crossterm::terminal::size() which throws errors in test environments
where TestBackend doesn't support terminal size queries.

Changed to use self.terminal.size().unwrap_or(24) to match the
graceful fallback pattern used in handle_create_key(), providing
a reasonable default height when the terminal size cannot be queried.
