fix: compatibility with HA 2026.3 mypy/ruff changes

- Cast energy_source flow_from/flow_to lists to fix mypy attr-defined errors
- Replace GridSourceType constructor with plain dict to fix TypedDict key errors
- Fix import formatting to satisfy ruff I001
- Pin pycares version / update requirements

Update tests.yml: Update checkout to v6
Update tests.yml: Python req from 3.13 to 3.14
Bump HA Version to 2026.3.2 (also stubs)
Bump Pycares to >= 5 (still have to check aiodns dependencies

Update __init__.py

HA 2026.3 update: Mypy fails to resolve flow_from on the TypedDict union, causing energy_source.get to return object. Fixed via type casting.
Also from typing import Any to from typing import Any, from typing import cast

Update flow_handler.py

In HA 2026.3, GridSourceType lost the flow_from/flow_to fields—they were replaced by flat fields (stat_energy_from, stat_cost, etc.). However, the runtime structure of the dict passed to the Energy Manager still works. Fix: Annotate as a plain dict[str, Any] instead of using the TypedDict constructor.

Lines 278 and 286 (grid_source["flow_from"].append(...) / grid_source["flow_to"].append(...)) will automatically work again, as dict[str, Any] allows for arbitrary key access.
