Use runtime_data in ws66i integration

[epenet]

Proposed change

Migrate the ws66i integration to use ConfigEntry.runtime_data instead of storing data in hass.data[DOMAIN][entry.entry_id].

• Added a Ws66iConfigEntry typed alias in models.py (alongside the existing Ws66iData dataclass).
• Updated __init__.py and media_player.py to use the typed config entry and entry.runtime_data.
• Updated the init test to check ConfigEntryState instead of hass.data.

Pull request overview

This PR migrates the ws66i integration from storing per-entry state in hass.data to using ConfigEntry.runtime_data, aligning it with current Home Assistant integration patterns.

Changes:

• Introduces a typed config entry alias (Ws66iConfigEntry = ConfigEntry[Ws66iData]) in models.py.
• Updates __init__.py and media_player.py to read/write integration data via entry.runtime_data.
• Adjusts the init/unload test to validate ConfigEntryState rather than hass.data.
