feat(card): badge differentiates expected vs unexpected skip

The level badge gains a third segment derived from level_cap_intent:
- amber 'gap?'   when the climb was capped by an UNDECLARED gap-sensitive N/A
                 (backup_restore / functional) — a likely-missing test (unexpected skip)
- muted 'expected' when capped by a DECLARED intentional N/A (reviewed, nothing to fix)
- nothing extra for a clean cap, a full climb, or a real failure.

Font-safe text labels (no emoji) so the SVG renders headless/anywhere. Badge
never inflates — it only annotates the cap the level already reflects.
