With only a MIFARE Classic present, identify randomly reported ISO15693
(bogus UID) or "LF tag" — because a flaky-link 14a miss fell through to
lenient checks:
- 15693 accepted any `uid` even without `found`; now requires found AND a
real E0-prefixed UID (a 14a miss leaves non-E0 garbage).
- LF reported a tag whenever lf.search() returned its (always-truthy)
sample-capture result; it can't confirm a tag without demod, so drop it
from identify (reliable LF detection is a follow-up).
- Retry the 14a scan (up to 3x) so a transient miss doesn't fall through.
3 tests (E0-gated 15693, bogus-UID + false-LF rejection).
