ui: decode and abbreviate long PLMN lists in the network monitor (v2.7.16)

EF.HPLMNwAcT fell back to raw hex: efFindDecoder uppercases the requested
name but compared it against the mixed-case registry names
('EF.HPLMNwAcT'), and the monitor passes no FID, so the lookup failed.
Name matching is now case-insensitive, which also fixes EF.PLMNwAcT,
EF.OPLMNwAcT, EF.PLMNsel, EF.KcGPRS and EF.LOCIGPRS for name-only callers.

The decoded HPLMNwAcT list can still be long (one entry per PLMN/AcT
combination), so netStatePlmnList keeps the first three networks and
appends a '… +N' counter; the row tooltip keeps the full decoded list.

- tests: registry case-insensitivity, netStatePlmnList limit, HPLMNwAcT
  summary abbreviation; help EN/RU.
