Fix facility allocated VLANs missing from resource summary/BQM

[kthare10]

Problem

/portalresources/summary?level=2&force_refresh=true (and the ABQM returned by /resources) never report allocated VLANs for facility ports: allocated_vlans is always null, even when facility slices are active.

Root cause

The two sides use different keys for facility VLAN allocations:

• Write: broker_simpler_units_policy.py builds the facility interface node_map as {graph}#{bqm_node.get_name()}#{bqm_cp.node_id}#{vlan}, so actor_database stores the components row with node_id = <facility name>.
• Read: AggregatedBQMPlugin called occupied_vlans(node_id=fac_sliver.node_id, ...). That passes the facility graph node ID (<port_nid>:facility+<name>), which never matches the stored name.

fim_helper.py already queries by facility name (node_id=f_name), which is correct.

Fix

Use fac_sliver.get_name() in both plug_produce_bqm_summary and plug_produce_bqm.

This changes reporting only. VLAN allocation (allocate_ifs) is not affected.

Testing

• Compile check only so far.
• After the broker is redeployed, verify that facility ports with active slices show allocated_vlans in the summary endpoint.
