URLs saved through the resource drawer historically landed in the docker
store under the runtime container key, which any stable record (including
an intentionally empty cleared one) outranks in the unified customUrl
projection, and which orphans on container recreation. On report ingest,
copy those records into the stable app-container guest key when it is
missing (cleared links stay cleared), healing saves stranded before the
drawer moved to the stable identity. Also read the runtime key before its
copy-if-missing container-name snapshot so the freshest write wins among
the docker-store fallbacks.
