Increase history storage limit to 50MB to match retention needs

Browse Source 
With 50 drives checked hourly over 30 days, history data can reach ~36MB
which exceeded the old 10MB limit causing constant file churn. Increase
to 50MB and make configurable via HISTORY_MAX_BYTES in .env.

Resolves #12
