Each abstract base class now carries a TYPE_LABEL: str attribute that
describes the device category in human-readable form:
AccessPointDriver → "Access Point"
FirewallDriver → "Firewall"
HypervisorDriver → "Hypervisor"
OSDriver → "OS"
ResidentialGatewayDriver → "Gateway"
StorageDriver → "Storage"
SwitchDriver → "Switch"
Concrete drivers can override TYPE_LABEL to express a more specific
category (e.g. LinuxDriver sets "Linux"). The backend reads this
attribute to expose a type_label in the DriverInfo API response,
replacing the hardcoded DRIVER_TYPE map in the frontend.
