fix: update admin_api migration dependency to existing events migration

0001_initial was referencing events.0011_dashboard_indexes which no
longer exists as a file on disk (the DB has it applied but the file
was removed). Updated dependency to 0010_merge_20260324_1443 which
is the latest events migration file present, resolving the
NodeNotFoundError on management commands.
