fix: Support GPT-5.1 reasoning.effort='none' in proxy (#16745)

Browse Source 
* fix: Add support for GPT-5.1 reasoning.effort='none' parameter

- Override Reasoning type to include 'none' effort value
- Maintains compatibility with semantic-router (requires openai <2.0.0)
- GPT-5.1 defaults to reasoning.effort='none' as of OpenAI SDK 2.8.0
- Override can be removed once semantic-router supports OpenAI SDK 2.x

Fixes #16741

* feat: Update to OpenAI SDK 2.8+ and Python 3.9+

- Update minimum Python version from 3.8.1 to 3.9 (3.8 EOL Oct 2024)
- Update OpenAI SDK requirement from >=1.99.5 to >=2.8.0
- Update semantic-router to >=0.1.12 with Python >=3.9,<3.14 constraint
- Update resend to >=0.8.0 (allows 2.x versions)
- Revert custom Reasoning TypedDict - now using native type from OpenAI SDK 2.8+

OpenAI SDK 2.8.0 natively supports reasoning.effort='none' for GPT-5.1,
eliminating the need for our custom type override.

* chore: Update poetry.lock with OpenAI SDK 2.8.1 and dependencies
