[Backport 7.81.x] Upgrade Python to 3.13.14

[Kyle-Neale]

What does this PR do?

Manual backport of #24019 to the 7.81.x release branch. Bumps Python from 3.13.13 to 3.13.14 across builder images and pins:

• Builder Dockerfiles (linux-aarch64, linux-x86_64, windows-x86_64)
• macOS PBS pins (PYTHON_PATCH=14, PBS_RELEASE=20260610, refreshed aarch64/x86_64 sha256)
• ddev Python version constant
• Refreshed .deps/image_digests.json

Built on top of #24021 (PBS pins extraction) which is already merged to 7.81.x, so pbs.env is a clean modify.

Motivation

The auto-backport bot failed to open this backport — see #24019 (comment). Creating it manually so 7.81.x picks up the latest Python patch release.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add qa/required if this PR needs QA validation, or qa/skip-qa if it does not. Exactly one of the two is required.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
