docs(narinfc/h7): add flight controller documentation

Add hardware documentation for the VOLOLAND NarinFC-H7 flight controller
including pinouts, serial port mapping, PWM output groups, and analog
inputs. Fix version badge to v1.17 and clarify RC_IN is wired directly
to FMU via RC_INPUT driver.

Based on work by @vololand and @hamishwillee from PR #26542.

+- ADC Pin4 → SPARE1_ADC1 (6.6V tolerant)
+- ADC Pin18 → SPARE2_ADC1 (3.3V tolerant)
+
+Additional internal ADC channels:
+
+- ADC Pin16 → BATT_VOLTAGE_SENS
+- ADC Pin17 → BATT_CURRENT_SENS
+- ADC Pin14 → BATT2_VOLTAGE_SENS
+- ADC Pin2 → BATT2_CURRENT_SENS
+- ADC Pin6 → RSSI_IN
+- ADC Pin8 → VDD_5V_SENS
+- ADC Pin11 → SCALED_V3V3
+
+## Building Firmware
+
+::: tip
+Most users will not need to build this firmware!
+It is pre-built and automatically installed by _QGroundControl_ when appropriate hardware is connected.
+:::
+
+To [build PX4](../dev_setup/building_px4.md) for this target:
+
+```sh
+make narinfc_h7_default
+```
+
+## Supported Platforms / Airframes
+
+Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos.
+The complete set of supported configurations can be seen in the [Airframes Reference](../airframes/airframe_reference.md).
