feat: Publish-to-catalog export for awards (edit in UI, version, ship to team)

Adds ExportAwardForCatalog(code, version): writes the selected award as a
catalog-format JSON ({"def":…,"references":…}) stamped with a version and with
user_edited cleared, ready to paste over internal/award/catalog/<code>.json. A
new release then propagates the change to the whole team via mergeCatalog —
unedited copies auto-upgrade, edited ones are offered the update.

UI: a version input + "Publish to catalog…" button in the award editor footer,
defaulting to one past the award's current version.
