Fix fitpro-build ABI packaging and fail loudly if it regresses

fitpro-build checks out the claude/fervent-newton-a25bb2 branch for
source but always runs under master's workflow definition (scheduled
nightly builds). The sed forcing ANDROID_ABIS in defaults.pri before
qmake, and the post-build ABI check, were dropped from this job by
e7abaeb while merging unrelated Apple Watch kcal work, silently
regressing nightly FitPro APKs to arm64-v8a-only.

Re-added the sed, and turned the diagnostic unzip -l checks into a
hard failure so a future regression breaks CI instead of shipping a
broken nightly release.
