feat(editor): F4.5b the device sheet for routers and home routers

Measured first: SheetRun now types into FILIUS' router and home router
panels, records five forwarding tables (holeTabelle) and steps in the
panel's table. Java turns a card address that passes the pattern but not
IP.ipCheck (".0.0.1") into null and the router panel throws; an empty
gateway is marked red yet taken; a refused table cell is stored as null;
a home router's DHCP client leaves its DHCP server running. None of the
nulls is adopted. The core's routeTableRows matches all five tables.

- doc: card addresses (the first card mirrored in the device's settings),
  router gateway, RIP, manual routes (a new row once all four cells pass,
  a cell, removal); the sheet reads cards with what their cable joins and
  the whole table
- editor: Java's tabs (general, each card titled by its address, the
  forwarding table greyed out under RIP; general, LAN, WAN on a home
  router); the open card's cable drawn active in Java's green
