Include and qualify Meshtext in RAK4631 Full Companion

Port Meshtext settings to verified atomic nRF52 storage and use the existing radio RNG and hardware entropy. Keep the ExtraFS boundary, GPS, contacts, channel count and 8 KiB stack unchanged; omit unused library data to fit the image. Require linked codec and Companion transport evidence and build the real RAK Full profile in CI. Add configuration and storage-failure regression coverage.
