fix: Pinned session TypeError, dead default models, get_history compat, i18n sync

- create_pinned_session built directly on aiohttp: the HA helper injects its own connector and raised TypeError on every setup and config flow - session lifecycle: closed in APIClient.shutdown, on failed setup, and in config flow validators; allow_redirects=False everywhere so 3xx cannot route past the pinned resolver - defaults: gemini-2.0-flash (shut down 2026-06-01) -> gemini-3.5-flash, deepseek-chat (retires 2026-07-24) -> deepseek-v4-flash - DeepSeek V4 disable_thinking via thinking request parameter - Gemini 3.x disable_thinking via thinking_level (MINIMAL, LOW for Pro) - get_history limit: no forced default/max in schema, storage layer clamps - translations: 6 locales caught up with strings.json, 2 orphan keys dropped - README: manual install path matches zip layout, model sections updated
