Subject: [PATCH 1/2] feat(schema): add bidirectional relationship identifiers
 and fabric-device links

- LocationSite: add devices (device__site) and fabrics (fabric__sites) reverse relationships
- InfraDevice.site: add identifier device__site
- InfraDevice: add fabric relationship (fabric__devices)
- InfraFabric.sites: add identifier fabric__sites; add devices reverse relationship (fabric__devices)
- InfraInterfaceVlan.vlan: add identifier vlan__svi
- InfraVLAN: add svi_interfaces reverse relationship (vlan__svi)
- Add 14-fabric-links.yml to assign all 10 devices to the evpn-lab fabric
