Switch CLI parsing to TextFSM and polish topology/workbench UX.

Use custom cli_templates plus community ntc-templates for LLDP and port traffic across ZTE/Huawei/Cisco/H3C/Juniper/Nokia, drop regex parsers, and surface Admin/Phy/Prot on port discover. Also batch-add topology NEs and tighten workbench branding.
