Deprecate and update python support (#650)

* Drop Python 3.9; add 3.13/3.14 and PyPy CI/tox coverage

- Require Python 3.10+; update classifiers, docs, and bumpr test env
- Expand GitHub Actions matrix (CPython, PyPy) and Flask exclusions
- Update tox for Flask 2/3 factors, PyPy envs with tox-only rpds pins
- Refresh test deps (pytest stack, twine) for newer interpreters
- Fix field tests for Python 3.14 partial/class attribute behavior
- Document changes under CHANGELOG 1.3.3

+::
+
+   * Drop support for Python 3.9 (EOL); require Python 3.10 or newer. [python-restx]
+   * Declare and test support for Python 3.13 and 3.14 (CPython). [python-restx]
+   * Expand GitHub Actions and tox coverage: PyPy 3.11 with both Flask 2.x and Flask 3.x; exclude Flask 2 on 3.13/3.14 where unsupported. [python-restx]
+   * Refresh test and release tooling (pytest, pytest-benchmark, pytest-profiling, twine) for newer interpreters. GitHub Actions pre-installs compatible ``rpds-py`` (and ``readme-renderer`` for PyPy 3.11) for PyPy jobs; tox pins ``rpds-py`` for local PyPy envs. [python-restx]
