The vendor's working install script (samples/uicc/applets/STK3) sends
`C9 22 <config> EF 08 C7 02 0000 C8 02 0000 EA 26 80 0A ... 81 18
<access>` - an applet config in C9 and memory quotas in EF. The RAM install
form now composes that prefix:
- "Applet-specific parameters (C9, hex)" -> `C9 <len> <value>`;
- "C7 / C8 memory quotas (bytes)" -> `EF <len> C7/C8 <2-byte int>` (4-byte
above 32767, GP 9.7);
- the prefix is prepended to the raw "Install parameters (hex)" field and
the server appends the STK part, giving `C9 EF EA`;
- `ramParamsPrefix`/`ramQuotaValue` are pure and tested (incl. the vendor's
`EF 08 C7 02 0000 C8 02 0000` form).
Also: `updateStkParamsHex` shows a hint naming the rejection reason (TAR not
a multiple of 3 bytes / menu ID > 7F / ADF AID not 5-16 bytes) instead of
silently emptying the field, and the UICC_SPECS.md install row notes that
`CA` sits inside `EF` and `CA`+`EA` together return 6A80.
