WgSharp 1.26.1006

Fix QR-code scanning from a webcam, which failed on real phone screens.
Reed-Solomon error correction in the decoder was broken (any single misread module made a code undecodable); fixed.
Perspective correction for tilted codes, adaptive thresholding, and noise-robust module sampling.
Camera: picks a ~720p format, enables auto focus/exposure/white balance, and corrects over-exposure from a bright phone screen.
Tunnel detail pane now wraps long keys and values instead of truncating them at normal window size.
