Config generates JavaScript boolean 'true' instead of Python 'True' causing NameError

Bug: app.conf contains 'true' (JavaScript) instead of 'True' (Python) on line 469. Causes NameError on startup.

Repro: Run NetAlertX v26.9.0 for days, app crashes with 'NameError: name true is not defined'. Check /data/config/app.conf line 469.

Fix: sed replace true->True in app.conf, restart container.

Root cause: Config generation writes JS booleans, not Python-compatible.
