ust: complete the USIM service table (147-150) + Services editor data fixes

The PWA's EF_UST_SERVICES stopped at 146; TS 31.102 §4.2.8 pins 147-150
(5MBS UE pre-configuration, Operator Controlled Signal Threshold per
Access Technology, A2X, IMS Data Channel Indication).  Add them and fix
the two test fixtures that assumed the 146-service table.

Resolve the three Services-editor FS mappings against the spec:
- eCall Data (89) -> EF.SDN 6F49 (+ EF.FDN 6F3A)
- eCall Data over IMS (112) -> EF.SDNURI 6FEF (+ EF.FDNURI 6FED)
- EARFCN list for MTC/NB-IOT (121) -> EF.EARFCNList 6FFD; "Extended
  EARFCN support" (100) is a capability, not a file.

Record the FID-first rule: the resolver and FS check key by (DF, FID),
the symbolic name is only a label; and clarify that the FS check is
card-only (independent of the cardless uicc_files.json list).
