feat(editor): F4.5a the device sheet for PCs, notebooks, switches and modems

Measured first: the new oracle SheetRun types 77 texts into FILIUS' own
settings panels and records what was marked red, what the device took and
what the field showed afterwards. Java's two judgements disagree (red text
taken, black text refused, any int as a modem port, a refused text dropped
without a word); here one rule decides both (packages/doc fields.ts), a
refused text stays marked in the field, and only what Java's model accepts
reaches the document.

- doc: settings.ts (name, label policy, addresses, IP forwarding, DHCP
  stopping the own DHCP server, LAN/WLAN with the wireless connection,
  switch SSID dropping its wireless hosts, retention time, cloud, modem
  port as its pair), sheet.ts (what the sheet shows)
- fls: modemPair/modemPort in one place
- editor: DeviceSheet beside the surface or below it on a phone, opened
  with the selection; every change one undo step
- not adopted from Java: the name overwritten by the MAC address, the
  access point search depending on unrelated devices
