Subject: [PATCH] STATUS: use P2=0C (phone-like, no FCP echo); v1.9.12

_send_status sent F2 00 00 -> the card echoes the FCP of the currently
selected DF on every poll/one-shot STATUS. Phones use P2=0C (no
response expected) to avoid that overhead. Keep P1=00 and the SIM/UICC
P3 distinction (SIM=0x23, UICC=0x00):

  CLA F2 00 0C P3

Affects one-time /api/status-poll and the automatic polling timer.

Version 1.9.11 -> 1.9.12 everywhere; SW cache otaman-v22 -> otaman-v23
