fix: replace puppetdbquery with native PQL queries (#457)

Replace deprecated dalen-puppetdbquery module with native puppetdb_query
function using PQL syntax to resolve URI.escape compatibility issues.
This is required to migrated to Puppet 8 (and kubernetes).

Changes:
- Remove dalen-puppetdbquery dependency from Puppetfile
- Replace query_nodes() calls with puppetdb_query() using PQL syntax
- Update 27 function calls across 18 Puppet manifests
- Maintain equivalent functionality with improved compatibility
