Handle both atom and string keys for packet received_at field

Browse source 
When packets go through Phoenix LiveView serialization, map keys can be
converted from atoms to strings. Add get_received_at/1 helper that handles
both formats to prevent KeyError when accessing received_at field.

This fixes the crash when the iOS app searches for callsigns and the
LiveView tries to render the tracked callsign's last seen time.
