Pull request overview

This PR fixes a bug in the Shelly inverter module where the phase count iteration was incorrect for the Shelly Pro3EM Gen2/Gen3 devices. The issue occurred because the em:0 status data is returned as a dictionary with many keys (not just the 3 phases), and using range(len(meters)) would iterate over all dictionary keys instead of just the three phases (a, b, c).

Changes:

• Fixed phase iteration for Shelly Pro3EM devices in inverter module by using range(0, 3) instead of range(len(meters))

• The inverter module lacks test coverage for the Shelly Pro3EM device (generation 2), which would have caught this bug. The counter tests include Pro3EM test cases (lines 177-191 in shelly_test.py) but the inverter tests (lines 257-282) skip this device model entirely. Consider adding Pro3EM test cases to the inverter test suite using the existing DATA_PRO_3EM_G2 test data to prevent similar issues in the future.

            elif "em:0" in status:
                meters = status['em:0']
                for i in range(0, 3):
                    if meters.get(f'{alphabetical_index[i]}_current') is None:
                        continue
                    currents[(i+self.phase-1) % 3] = (float(meters[f'{alphabetical_index[i]}_current']) * self.factor
                                                      if meters.get(f'{alphabetical_index[i]}_current') else 0)
                power = float(meters['total_act_power']) * self.factor
