Add JP_STRICT mode: enforce MAX_TEXT_LEN for ARIB STD-T108 compliance

Browse source 
JP_STRICT limits MAX_TEXT_LEN to 1*CIPHER_BLOCK_SIZE (16 bytes) to keep
TX time under 4 seconds on SF12/BW125/CR4-8 (Japan LoRa settings).

SF12/BW125/CR4-8 airtime:
  60 bytes total packet = ~3809ms (within 4s limit)
  packet overhead ~44 bytes, leaving 16 bytes for text payload

Enabled only for WioTrackerL1 and RAK_WisMesh_Tag builds.
