Fix packet retention config to read env var at runtime

Browse source 
Move packet_retention_days configuration from config.exs (compile-time)
to runtime.exs so it properly reads the PACKET_RETENTION_DAYS environment
variable at runtime instead of baking in the default value during build.

This fixes the issue where the app was using 7 days retention despite
PACKET_RETENTION_DAYS being set to 1 in the deployment, causing disk
to fill up with 54GB of old partition data.
