v0.99.102

In-app updates failed on printers with older BusyBox (#993) — release zips were verified with unzip -tqq, but BusyBox only gained unzip -t in 1.32, so the AD5M (1.29.3) and K1 (1.31.1) rejected an intact download outright and every in-app update and Moonraker install failed. Validation now tries python3 zipfile.testzip() first, gated on zlib since the AD5M's Python 3.7 has none, and degrades to a structural unzip -l probe rather than declaring a good archive corrupt. Verified on K1, AD5M and CC1 hardware.
The K2 could not install a zip release at all — its OpenWrt firmware ships no unzip binary and no BusyBox applet, only python3, so the pre-download check rejected every update with an apt-get hint that does not apply there. The check now asks whether the system can read a zip by any means, extraction gained a Python fallback, and both paths force the exec bit on install.sh and bin/ members so the extracted installer can actually run. Verified on K2 hardware.

Sonic Pad documentation now states that SonicPad-Debian is the only tested firmware.
