genSp: unciphered packets drop CPL prefix + prominent PoR status; v1.9.5

pySim encode_cmd transmits the 2-byte CPL only when ciphering is
applied; unciphered packets start at CHL. genSp always emitted it,
so every SPI1=0x00 packet diverged from the pySim reference at byte 0
(sp-verify MISMATCH) and carried a length octet pair real cards need
not expect.

- genSp output: bytesToHex(ciphering ? packet : packet.subarray(2));
  MAC input unchanged (still covers the virtual-CPL frame, matching
  pySim's sign-then-strip convention)
- Secured packet page: PoR verdict now rendered prominently in a
  dedicated text-base semibold line ('PoR: por_ok' green / other
  statuses red) above the small detail line; hidden when no PoR was
  requested or the ENVELOPE failed
- sp.test.js: three unciphered expectations updated to CHL-first form;
  ciphered vectors untouched (byte-identical)
- version 1.9.4 -> 1.9.5 everywhere; SW cache otaman-v15 -> otaman-v16
