lf search false positive Indala / lf em 410x reader fails on T5577 emulating EM4100

[ronniemerino]

Environment

• Hardware: Proxmark3 X with portable LF antenna (LF-ANT-500uH)
• Firmware: Iceman/master/v4.21611
• OS: Windows 11
• Client: Iceman/master/v4.21611

Steps to reproduce

1. Take a blank T5577 card
2. Run lf t55xx detect → correctly identifies T55x7
3. Run lf em 410x clone --id 0001020304
4. Run lf search → false positive Indala instead of EM4100
5. Run lf em 410x reader → no output, nothing detected
6. Run lf t55xx detect → fails after cloning

Expected behavior

• lf search should detect EM4100 ID correctly
• lf em 410x reader should read and display the ID

Additional notes

• Flipper Zero reads the same card correctly as EM4100
• Card physically works
• lf t55xx wipe + lf t55xx detect works correctly on blank card
• lf t55xx sniff captures real write commands confirming it IS a T5577
• Issue reproduced on both v4.18994 and v4.21611
• lf search consistently returns Indala false positive with varying raw lengths (68, 93, 581)
