The delays.rx_delay_base config value was stored and reported but never
applied. Now that the core dispatcher implements MeshCore's flood
reception-quality delay, feed it through:
- set dispatcher.rx_delay_base from delays.rx_delay_base at startup and
re-apply it on live config updates of the delays section (web API
saves already pass that section)
- point the mesh CLI get/set rxdelay at the delays section; it read and
wrote repeater.rx_delay_base, which nothing consumes, so the CLI knob
was silently dead
- delegate RepeaterHandler.calculate_packet_score to the shared core
packet_score (same firmware packetScoreInt formula, one impl)
Suppression works through the existing engine seen-cache because it
dedupes at process time, after the dispatcher hold. Default remains 0
(delay disabled), matching firmware.
