feat(fls): import DHCP, port forwarding and modem settings

importProject carries the DHCP client switch and server settings (hosts
and home routers), a home router's port forwarding rows and a modem's
pairing into the model; the core gains the types, ported from Swift.
The Swift oracle writes them too, and they match on the 13 files Swift
reads completely. Configuration text is now trimmed throughout, as Swift
trims every value it reads (routes and firewall rules included).

Outside those files Swift switches every DHCP server of the Internet
examples off: their "aktiv" refers to a shared Boolean it cannot follow.
