fix(powerdns): fix SQLite directory permissions for pdns user

The /opt/poweradmin/ directory was owned by www-data:www-data (755),
but pdns runs as the 'pdns' user which had no write access to the
directory. SQLite requires write access to the database directory to
create journal/WAL files (powerdns.db-journal, powerdns.db-wal).
Without this, pdns fails to start.

Changes:
- Set directory group to 'pdns' instead of 'www-data' so pdns user
  can create SQLite journal/WAL files (via group write 775)
- Apply same permissions fix in update_script (ct/powerdns.sh)
- Fix msg_info -> msg_ok for 'Created Service' completion message

Fixes #12572
