abbterra: split status block to respect 31-byte RT38B01 frame limit
The status block (12 registers × 2 words = 24 words) was read as a single Modbus request, producing a 53-byte response that overflows the RT38B01 433 MHz radio module's 31-byte frame limit. Dissolve the status block into individual registers with readSchedule:update so queuedRequests sends them one at a time (max 9 bytes per response). The deviceInfo init block (8 words → 21 bytes) is left untouched. Bump to 1.15.0+etm6. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
