create_data_dirs now chowns data directories to the correct mapped
UID for rootless podman (host_uid = 100000 + container_uid).
Previously only Grafana (UID 472) was handled. Now all containers
get the correct ownership:
- Bitcoin Knots: 100101 (container UID 101)
- Grafana: 100472 (UID 472)
- LND: 101000 (UID 1000)
- MariaDB: 100999 (UID 999)
- Postgres: 100070 (UID 70)
- All others: 100000 (UID 0, root)
Without this, containers fail with "Operation not permitted" on
chown during startup because rootless podman restricts UID operations.
