Manual reset cost tracker fails after 2 days

[BottlecapDave]

Describe the bug

When you have a cost tracker that hasn't been reset for more than 2 days (e.g. older than the previous available rates), then you start getting errors in the form of

Traceback (most recent call last):
  File "/config/custom_components/octopus_energy/electricity/__init__.py", line 41, in calculate_electricity_consumption_and_cost
    rate = next(r for r in rate_data if r["start"] == consumption_from and r["end"] == consumption_to)
StopIteration

During handling of the above exception, another exception occurred:

    self._recalculate_cost(current, consumption_data.tracked_consumption_data, consumption_data.untracked_consumption_data, rates_result.rates)

Exception: Failed to find rate for consumption between 2024-12-31 08:00:00+00:00 and 2024-12-31 08:30:00+00:00

Reproduction steps

1. Setup a cost tracker with manual reset enabled
2. Don't reset the cost tracker for 2 days

Expected behaviour

The cost tracker should continue to work for more than two days or a repair notice should be raised stating the cost tracker needs resetting. Either way, the sensor should not throw an error
