4.1.4: QR sharing, venv tarball, flash script improvements
QR Channel Key Sharing: - Admin-only QR generator in about.html (was visible to all) - QR button for saved keys on account page - Fixed about() route missing channel status vars (bug) Pi Build Optimization: - Pre-built venv tarball support (39MB zstd, skips 20+ min compile) - setup.sh auto-detects and extracts tarball if present - Strip __pycache__/tests before tarball (295MB → 208MB) Flash Script Improvements: - flash-image.sh now uses config.json for headless WiFi setup - Consistent wipe prompt on both flash scripts - pull-image.sh re-enables auto-expand before shrinking Build Docs: - Added zstd and jq to pre-setup apt-get - Documented fast build option with pre-built venv 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
