Calculate differences between battery energy readings and preset that as the sensor value for battery charge or discharge energy. This will hide the actual values read over modbus, but in favor of trying to present something closer to lifetime energy that the hardware can't provide.

- Around line 2614-2625: Update the battery energy reading logic to avoid
rebasing on a single lower Modbus reading: keep `_prev_raw` unchanged until a
lower value is confirmed on a subsequent poll, then rebase and clear the pending
value. Initialize the pending-rebase state alongside the other fields, and clear
it when a reading is not lower.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Give each migrated entry its own repair issue ID.
If two config entries have reset-cycle values below two, both migrations create battery_energy_reset_cycles_changed under the same domain. The issue registry identifies issues by domain and issue ID, so it cannot retain a separate warning and old value for each entry. Include config_entry.entry_id in the issue ID.

Clear the lower-reading count after an invalid poll.
If a lower reading is followed by None, zero, or the sentinel value, _process_data() returns without clearing _lower_polls. A later lower reading can then trigger a rebase even though the lower readings were not consecutive. If those readings are transient faults, the next normal reading adds most of the raw lifetime counter to the total. Clear _lower_polls on the invalid-reading path, and test a lower–invalid–lower sequence.

This PR tries a new approach to dealing with resetting battery energy. In the past I had always favored not altering the data returned over modbus, but in the case of battery energy it might actually be more appropriate to present altered data.
Some batteries (LG, BYD) do not have lifetime energy counters. SolarEdge's cloud platform appears to simulate lifetime values by summing delta energy, so lost telemetry leaves the totals incomplete. This is not revenue grade metering and we don't want user to have to rely on cloud for this, although a comparison to the cloud values would be interesting.
Whit this PR battery energy sensors here will try to do the same: it adds each increase in the register to its own running total, so the total never goes down. A register that goes backwards is treated as a new reference point and adds nothing. This also works for batteries with true lifetime counters.
This replaces a previous approach where we would still treat the sensor as lifetime and give the user an option to allow resetting, but did not alter the values modbus returned. The delta values for energy counters hide the actual values read over modbus. Options for allow battery energy to reset and cycles to reset are made obsolete and have been removed. They're not being removed from the config entry yet though, so an easy downgrade is possible if this turns out to be a bad idea.
