Drop 10 dead parser-compat columns (srccallsign, dstcallsign, origpacket, body, header, alive, posambiguity, symboltable, symbolcode, messaging) and move 14 display-only columns into a single `data` JSONB column (PHG, telemetry, radiorange, information_field, format, posresolution, position_ambiguity, luminosity, rain_midnight). Reduces row width from ~70 to ~48 columns. Table is ephemeral so migration uses DROP/recreate. Also fixes snow_24h -> snow bug in weather check query and adds null byte stripping for JSONB string sanitization.
