Replace wrapt patching with truststore integration

Modernizes the package architecture by replacing complex monkey-patching
with truststore's native SSL context injection. This provides better
compatibility, reliability, and aligns with the Python ecosystem direction.

Key changes:
- Replace wrapt dependency with truststore (>=0.8.0)
- Update Python requirement to >=3.10 (truststore minimum)
- Simplify wrapt_requests.py from ~80 lines to ~12 lines
- Remove complex HTTPAdapter patching in favor of inject_into_ssl()
- Update package description and documentation
