[TSM.ID].[11031972] fix: 3Z Zero Error — fix 16 module test failures

FIXED:
- xcu-aegis: test data too few blood flow pulses (3 < threshold 5)
- xcu-anti-debug: integer overflow in seed calc (sum::<u8> panic)
- xcu-anti-dump: same overflow bug
- xcu-browser-engine: same overflow bug
- xcu-db-sync: same overflow bug
- xcu-fingerprint-fuzz: same overflow bug
- xcu-hardware-token: same overflow bug
- xcu-jailbreak-detector: same overflow bug
- xcu-key-rotation: same overflow bug
- xcu-network-isolate: same overflow bug
- xcu-pin-pad: same overflow bug
- xcu-pkx-enforcer: same overflow bug
- xcu-tamper-proof: same overflow bug
- xcu-codec-av1x: OBU header byte 0x12 decoded TempDelimiter not SeqHeader
- xcu-codec-h265x: NAL byte 0x28 decoded IdrNLp not IdrWRadl
- xcu-omniscience: FSK test wave had amplitude>0.8 triggering AM path

All 142 modules now pass: cargo test --workspace --lib -D warnings
