v1.12.6 — Reset API budget on Husqvarna Application rotation

Fixed

• API-budget counter now resets on client-ID rotation. ApiBudgetTracker only rolls over at the calendar-month boundary, which is correct for a stable key — but a user rotating to a new Husqvarna Application (fresh server-side quota) was left with the old counter until the 1st of the next month, so hub_api_budget_remaining lied and the is_exhausted auto-stop could still fire on a fresh budget. Reauth and reconfigure now detect a changed CONF_CLIENT_ID and zero the persisted counter via async_reset_api_budget_store before reloading. Same-client_id reauth (just refreshing a rotated secret) preserves the counter.

Added

• ApiBudgetTracker.async_reset() and module-level async_reset_api_budget_store(hass, entry_id) helpers in base_coordinator.py.
