feat(licenses): Task #25 step 1 — SourceBadge in atomic-controls + correct LicenseRuleBadge labels

Per the SDK-Modul Attribution-Matrix (project_sdk_module_attribution_matrix.md),
the controls/atomic-controls listings render canonical_controls directly and are
the highest-audit-visibility integration point for Stufe 3.

Two changes:

1. atomic-controls/page.tsx: embed <SourceBadge controlUuid={ctrl.id} compact />
   next to the existing badge row in each control item. The badge fetches
   /api/compliance/licenses/source-info/{uuid} on first hover and reveals the
   source regulation, license type, and attribution text in a tooltip.

2. control-library/components/helpers.tsx: fix LicenseRuleBadge labels. The
   existing pill said "Free Use / Zitation / Reformuliert" — exactly the
   inverted understanding of the rules that Task #21 surfaced. Corrected to
   R1 (verbatim, Hoheitsrecht/PD), R2 (verbatim + attribution), R3 (identifier
   only). Added native title attribute for hover-explanation; the existing
   ControlListItem in control-library now shows the right semantics
   without any other code change.

Next module per matrix: VVT (Bundeslaender-Vorlagen) and DSFA.
