OTA status stays on the SP page, not in the header; v1.9.7

pysimSendOta wrote its progress/verdict into #pysim-status - the shared
header line owned by connect/equip/poll logic - clobbering the card
status shown under 'Equip card'. OTA outcomes now live exclusively on
the Secured Packet page:

- send start: small gray 'Sending OTA...' in #sp-send-result
- verdicts: big #sp-por-status + details line, as before
- header #pysim-status untouched by OTA flows

Version housekeeping: v1.9.6 -> 1.9.7 everywhere; SW cache
otaman-v17 -> otaman-v18. Also realigns pyproject.toml which the
multi-amend rounds had left stale at 1.9.5.
