Inside state Receiving, override the parent Configured state chart handler on(ConfigApplied) => Idle with on(ConfigApplied) => ResumingRx. ResumingRx entry (try_start_rx_hw) re-enables RX on the chip with the new modulation once apply_set_config has finished the SPI write + calibration, and transitions back to Receiving on StartRxOk.
Net effect: SET_CONFIG issued while the radio is in continuous RX no longer kicks the radio (and therefore the OLED) out to idle. The RX ring is still cleared by apply_set_config; callers never need to re-issue RX_START after SET_CONFIG.
This matches donglora-protocol 1.1.0 §3.5 and §6.3 normative behavior.
