feat: aliro-bench-profile CLI + per-APDU latency probes

New `aliro-bench-profile` entry point drives the applet's INS_DIAG_*
commands over PC/SC at two iteration counts (N=4 / N=16 by default) and
computes per-op cost as the slope, factoring out APDU round-trip + any
one-time Signature.init setup. Reports HMAC, ECDH, ECDSA sign, and
AES-GCM 137B costs side by side, then reconstructs an AUTH1 budget
using the per-primitive counts from the applet's processAuth1 flow so
we can compare the reconstructed estimate against bench-test wall-clock
and see how much of AUTH1 is crypto vs TLV parsing / I/O.

Also extends `aliro-bench-test` to time SELECT / AUTH0 / AUTH1 / total
via time.perf_counter() bracketing each transmit() call. The TransactionResult
now carries a latencies_ms dict, threaded through all return sites so both
success and failure paths print the new "APDU latencies (ms):" block.
Made the 1.78x AUTH1 wall-clock speedup from the 4-bit GHASH commit
quantifiable on real hardware (5,795 -> 3,244 ms).
