feat(store): advisory-version badge for federated entries

Store cards + detail-sheet now prefix the version pill with
`~` and attach a tooltip for federated entries (MCP / n8n /
Temporal). Upstream services don't honour semver, so the
version pill is a label, not a contract — the tilde says
"this number may change without a version bump."

Three render sites updated to stay visually consistent:
- compact card pill in grid view
- expanded card pill row
- detail-sheet header pill cluster

EN + DE l10n entries added (`storeAdvisoryVersionTooltip`)
and `app_localizations.dart` regenerated.

dart analyze clean; flutter test green (11 tests).
