fix: pre-liberation review — frames dir, wigle config GET, debug redis-keys endpoint

CRITICAL:
- frames.py: FRAMES_DIR corrected to /tmp/adacam/pics
- frames.py: graceful handling when capture not started

IMPORTANT:
- wigle.py: added GET /api/1/wigle/config endpoint for Varroa
- app.py: added GET /api/1/debug/redis-keys endpoint for GPS troubleshooting
- install.sh: removed python validation that runs from wrong directory
