fix(ci): copy events metadata to top-level artifact directory

The packaging script only placed all_events.json.xz in an events/
subdirectory, but the firmware advertises the metadata URI at the
board directory top level. New build targets added after the
Jenkins-to-GHA migration had no legacy top-level copy, causing
QGC to get a 404 when fetching component metadata.

Fixes #26963
