Drop the header row, tighten name-to-count spacing

Confirmed (again, by rendering into a captured pty and inspecting the
character grid) that whiptail always renders a blank line between the
instructional text and the checklist box itself, with no parameter to
remove it — so a header "directly above the purple box" isn't achievable
no matter how it's built. Per this session's direction: drop the header
line entirely and just tighten the gap between the count and the service
name (was up to 15 chars of mostly blank space from the wide count field
sized to match the now-removed header label; down to ~5).

Verified end-to-end in the same pty harness: rendered the real dialog,
sent actual keystrokes to toggle two items (one plain, one with a
double-digit count), captured the raw whiptail selection output, and
confirmed the existing "extract text after the last space" logic still
pulls the correct plain service names back out.
