Implement pump flow monitoring and UI normalization enhancements

- Rust: Add `MIN_PUMP_FLOW_ML` constant and logging for insufficient pump flow with fault handling.
- UI: Normalize config fields to maintain consistency and prevent false dirty flags after round-trips.
- KiCad: Update board zone settings for `PlantCtrlESP32` and `MPPT`.
- IntelliJ: Add `.idea` configurations for project setup and inspections.
