feat: add support for python 3.14 and replace django-fsm to django-fsm-2

[vinitkumar]

Description

Add support for Python 3.14 by extending the test matrices, CI configuration, project classifiers, and requirement files, and enhance the pip-tools installation in the compile script.

New Features:

• Support Python 3.14 in test requirement sets across Django and CMS version combinations

Enhancements:

• Pin pip to version 24.3.1 and add the --break-system-packages flag when installing pip-tools in the compile script

CI:

• Include Python 3.14 in the GitHub Actions test matrix

Documentation:

• Add Python 3.14 to the project classifiers in pyproject.toml

Tests:

• Generate new requirement files for Python 3.14 for all Django and CMS variants

• I have added or modified the tests when changing logic
• I have followed the conventional commits guidelines to add meaningful information into the changelog
• I have read the contribution guidelines

This PR adds Python 3.14 support across CI, project metadata, and test configurations, pins pip-tools upgrades to pip 24.3.1 with system-break flags, and migrates the finite-state machine dependency from django-fsm to django-fsm-2.

Hey there - I've reviewed your changes - here's some feedback:

• I don’t see any actual code changes replacing django-fsm imports or usage with django-fsm-2; please ensure your application code is updated to use the new package and remove old references.
• The new py314 requirement files are almost identical to existing ones—consider templating or generating them to avoid maintaining so many near-duplicate files in the future.
