feat: toolkit block emphasised + auto CA/EA from the CAP (v3.6.32)

The RAM install form's toolkit parameters are the make-or-break field for
toolkit applets, and CA vs EA is easy to get wrong (the earlier live 6A80s).

- "SIM/UICC Toolkit parameters" is now an accented bordered fieldset (blue
  border/legend, always visible in the cap / install / make-selectable
  modes) with the checkbox in the legend and the fields inside.
- ramCapToolkitMode(imports) maps the CAP's linked libraries to the install
  parameter family: sim.* (AID tree A0000000090003FFFFFFFF89...) -> SIM
  Toolkit (Tag CA), uicc.* / uicc.usim.* (A0000000090005FFFFFFFF89...,
  A0000000871005FFFFFFFF89...) -> UICC Toolkit (Tag EA) - family-based, so
  access-only applets get the right field too.  Applied when the block is
  enabled and when the CAP is swapped while it is on, with a "detected from
  the CAP" hint under the select; no CAP keeps the manual choice.
- Rebuilt style.css for the new accent classes; tests pin the fieldset and
  the family mapping.
