Add VLAN table + per-connector VLAN tags (structure only -- no VLANs in NetBox yet)

Browse Source

Inspired by a reference diagram the user liked (VLAN legend/mapping table,
per-port VLAN info) but explicitly without the literal switch CLI config
dumps that diagram also had.

- export_topology.py: pulls ipam.VLAN (with prefixes) plus, for every
  edge whose endpoint is a real Interface, that port's mode/untagged/
  tagged VLANs. NetBox has zero VLANs defined right now, so this comes
  back empty/null throughout -- the plumbing is real, the data just
  isn't there yet.
- generate_drawio.py: renders a VLAN table (VLAN/Name/Description/
  Subnet/Site) at the top of the diagram. With no VLANs it shows an
  explicit dashed 'not configured yet' placeholder row instead of
  either fabricating VLAN numbers or silently omitting the table.
  Connector labels get a 'V<id>' / 'V<id>,<id>T' suffix per side
  whenever that port actually has VLAN config -- currently a no-op,
  activates automatically the moment VLANs exist in NetBox.
