fix: passband RX update now uses full Doppler round-trip instead of pure passband mapping

When adjusting RX in passband mode (via +/- buttons or slider), the old code used TransponderMapper.mapDownlinkToUplink (pure passband mapping without Doppler compensation), producing ~10kHz error at LEO velocities. Fix: use DopplerFrequencyCalculator.computeUplinkFromDownlinkWithOffset for the full TX-from-RX round-trip, matching the RX→PASSBAND button onClick logic. Also fixed frame mismatch: position now uses txLow/txRange (Doppler-shifted frame) consistently.
