The vendored gns3fy Node model and its nodes_inventory() now carry the
node's netmiko_device_type field, and get_device_ports_from_topology()
resolves the Netmiko device type from it first, falling back to the
device_type:<type> tag. Nodes created from a template inherit the value
from the template automatically, so automation tooling gets the correct
Netmiko driver without tags.
The vendored gns3fy copy keeps its type lists as literals (the module is
shared with the standalone MCP service and cannot import server enums),
and CONSOLE_TYPES had drifted: 'ssh' and 'docker_exec' were missing while
both are valid server-side. Impact: the copilot topology reader validates
the whole node list in one pydantic pass, so a single vendor NOS node
(console_type 'docker_exec') made it drop the entire project and return
zero devices to every copilot device tool.
Add the missing values plus drift tests asserting the vendored lists
cover the server enums (skipped when ai-features extras are absent).
