ci: run CI on Python 3.14

The lockfile and local development environment are already on 3.14; CI was
still installing 3.13, so the interpreter under test was not the one the
project is developed against. Applied uniformly across ci, docs and
integration, including the `uv sync --python` pins that would otherwise
pull a second interpreter into the same job.
