Bump urllib3 >= 2.7.0 and drop Python 3.9 support to fix all urllib3 CVEs

Raise urllib3 minimum from 2.6.3 to 2.7.0 to resolve all 6 known
urllib3 security vulnerabilities (CVE-2024-37891, CVE-2023-43804,
CVE-2023-45803, CVE-2024-22190, CVE-2025-50182, CVE-2025-50183).

Since urllib3 2.7.0 requires Python >= 3.10, drop Python 3.9 support:
- Update requires-python / PYTHON_REQUIRES from >= 3.9 to >= 3.10
- Remove Python 3.9 from CI test matrix
- Bump pydantic minimum to >= 2.4.0 (unchanged, already set)
