Savings total not updating

Pull request overview

Fixes an issue where savings_total_* entities could fail to increment by ensuring required tracking attributes are initialized, alongside a refactor to compute charge-limit percentages on-demand and new optional device/plant filtering for Fox and SolaX integrations.

Changes:

• Initialize savings_total_predbat tracking attributes (last_updated, start_date) so totals can increment reliably.
• Remove persisted charge_limit_percent* arrays and compute percent values from kWh when publishing/logging.
• Add optional filtering for Fox devices (inverter_sn) and SolaX plants (plant_sn) plus small robustness improvements.
