v1.0.27 — Configurable LoRa airtime (duty-cycle) limits

Adds two new fields to the LoRa section of the WiFi config portal:

  • 15s limit (%) — short-term airtime cap (rolling ~15 second window)
  • 1hr limit (%) — long-term airtime cap (rolling ~1 hour window)

When the measured LoRa airtime exceeds either threshold, TX is paused
until the rolling window drops back below the limit. Range 0–25 %
with 0.1 % resolution. 0 = disabled (default).

Useful for self-imposed regional duty-cycle budgets — e.g. EU868 users
can set 1.0 on the 1hr limit.

Settings are persisted to EEPROM and survive reboots.
