Code-review fixes: bad-format visibility, view-aware sync, counter hygiene

- The RAM step line (and the plain send's PoR line) now name a bad-format
  failure ("bad format 02 (wrong length)") instead of reading "PoR ok": the
  step record carries por_bad_format_name and ramStepLine renders it.
- ramSyncCounter follows the view the notice came from ('ram'/'sp' - preset
  and keyset selectors alike) and refreshes the keyset labels after a sync.
- The ETSI-release line no longer hides behind the memory block (it needs
  only the ELF list).
- /api/send-ota reports final_cntr only for a packet the card accepted: the
  failed-envelope path used to persist the packet's own counter on a
  rejection (the audit trail's small bump on cntr_low).
- _ram_detect_format's docstring corrected (both expanded codings execute on
  the live ISD; the earlier bad format was a length-mismatched template).
- Tests: ramStepLine bad format, the view-aware notice, the accepted/rejected
  final_cntr cases, and an end-to-end /api/counter-probe endpoint test
  (400s, no write on a rejected walk, accepted+1 stored).
- sw cache simple-v356.
