This was reported incorrectly earlier using a variable that was never set. That variable and related (unused) channels have been removed. This also updates the PV pool tests to ensure that the distribution results are accurate. Signed-off-by: Sahas Subramanian <[email protected]>

Pull Request Overview
This PR fixes an incorrect calculation of succeeded_power during PV power distribution and removes unused variables/channels.
- Updates the succeeded_power logic in the PV inverter manager to subtract both failed and remaining power.
- Adjusts test assertions and expected values in the PV pool tests to reflect the new calculation.
- Revises release notes to document the correction.

- [nitpick] Consider adding additional tests to cover edge cases where the request.power significantly deviates from component defaults, ensuring comprehensive coverage of the new succeeded_power logic.

[nitpick] Consider adding a brief comment or updating the docstring here to clarify why the succeeded_power is calculated as request.power minus both the failed_power and remaining_power.

[nitpick] A comment explaining why the succeeded_power calculation in this branch excludes failed_power (compared to the previous branch) would improve maintainability and clarity.
