Update CI workflow test matrices for Python 3.10/3.14 and React 19, and align dev dependencies for missing Python imports

[Copilot]

This updates workflow test coverage to match the requested runtime targets (Python 3.10, Python 3.14, and React 19) and adjusts dependency handling to resolve missing-library import failures.

• Workflow matrix updates

  • Updated test job Python matrix from ["3.8", "3.12"] to ["3.10", "3.14"]
  • Updated test-react job React matrix from ["18.2.0"] to ["19"]

• Python library/testing setup

  • Updated requires-dev.txt to use dash[dev,testing]>=2.0 (removed ci extra)
  • Added explicit numpy and pandas to requires-dev.txt so required imports are present for tests/runtime paths
  • Removed the temporary workflow workaround that installed requires-dev.txt directly in CI jobs
  • Added an unreleased changelog entry describing the workflow/runtime and dependency updates

• Scope

  • Updated .github/workflows/python-test.yml
  • Updated requires-dev.txt
  • Updated CHANGELOG.md
  • No changes to application runtime code or component behavior

Looks like we need some updates for the libraries in Python for 3.14 support and testing.

Updated in commit 2096443.

I changed dev dependencies from dash[ci,dev,testing] to dash[dev,testing] in requires-dev.txt so the Python 3.14 workflow install path no longer pulls the problematic y-py/Jupyter CI chain, and added a changelog entry for this update.

We need the ci... I guess drop the 3.14 to 3.13 instead.

I switched the workflow Python matrix to 3.10/3.13, restored dash[ci,dev,testing] in requires-dev.txt, and updated the changelog entry to match.

Go back to 3.14 and fix the issues for missing libraries, since 3.13 is also running into the same issue.

I restored the matrix to Python 3.10/3.14 and updated both CI install steps to include uv pip install -r requires-dev.txt so missing test libraries (like numpy/pandas) are installed.

Drop the ci implementation on the dev and work through adding the missing imports in the code to get it to function properly.

Done in bf0afb7.

I removed the CI-extra dependency path from dev (dash[dev,testing]), added explicit numpy and pandas dev requirements so imports resolve from .[dev], and removed the temporary workflow requires-dev.txt install workaround.

No UI changes in this update (CI/dependency-only change).
