OTA send UX + PoR transparency; v1.9.4

- pysimSendOta: Response Parser filled strictly from decoded PoR
  (por.decoded) for both SPI2 variants; envelope SW/failures no longer
  leak into it — they render in a new inline result line (#sp-send-result)
  next to Send to Card, always including SW on failure
- Default-level stderr tracing per send (no flags needed):
  'OTA SEND: SPI .. KIc .. KID .. TAR .. CNTR .. LEN ..B CHUNKS N',
  'OTA SEND FAILED: chunk N SW xxxx' and
  'OTA PoR[envelope|sms-submit]: status=.. TAR=.. CNTR=.. PCNTR=..
  RPL=.. RHL=..' (+ compact summary / undecodable raw / none fallbacks)
- _decode_por: surface every parsed PoR field verbatim (cntr, rpl, rhl,
  cc_rc, raw) instead of status/tar/pcntr only
- genSp: CNTR normalization padEnd -> padStart so short input like '1'
  becomes 0000000001, not 1000000000 (counter is big-endian 5 bytes)
- tests: TestDecodePor completeness + cntr_low field-report cases

Version 1.9.3 -> 1.9.4 everywhere; SW cache otaman-v14 -> otaman-v15
