ui: net-sim Home network button; compact HPLMNwAcT monitor row (v2.7.18)

- netstate.home_plmn(): the card's home network — EF.HPLMNwAcT first
  record (the HPLMN per TS 31.102 4.2.5), falling back to the IMSI with a
  2-digit MNC.  Exposed as state.network.home in /api/net-state.
- The net-sim parameters get a Home network button next to Random roaming
  operator: it fills MCC/MNC and reports the source (EF.HPLMNwAcT/IMSI).
- The monitor's HPLMNwAcT row now shows only the first network (code
  only) plus a '… +N' counter; the tooltip keeps the full decoded list
  with the access technologies.
- tests: netstate home_plmn cases, netsim button handler, updated
  netstate expectations; help EN/RU.
