# Init container that waits for Collabora and configures WOPI on every pod start.
#
# The Drive chart's configure_wopi Job is designed for ArgoCD PostSync hooks
# and only runs on `sunbeam apply`. On server restart, no one re-triggers it,
# so WOPI editing silently breaks. This init container fixes that — every time
# a Drive backend pod starts (restart, rollout, scale-up), it waits for
# Collabora and runs trigger_wopi_configuration before the main container.
