For developers: what the fix changed

The fix restricts access to the OAuth2 validation routes by replacing `_access: 'TRUE'` with specific administer permissions in the routing files for Box, Quip, and Slack. It also updates `ValidationControllerBase::validate` to clear the initialisation state after use and ensures it is not empty before comparing it to the request state.

Also in this release The release also fixed a lock contention bug in `refreshSystemAccessToken()` and added automated tests.

8.x-1.1 to 8.x-1.2 2 commits, 13 files including 2 tests.

Tell me who you are, what your organisation does, and what you need. That might be a Drupal site that needs looking after, an upgrade to get done before December, or an agency that needs Drupal cover.

If I can help, I'll say so and suggest a call. If I can't, I'll tell you straight away rather than waste your time.

For context: I work mainly with UK membership bodies, charities and research organisations, and with the agencies that look after their websites. Not recruiters.

Or start smaller and connect with me on LinkedIn. That's where I post what I find digging around in charity and grants data, and where the free tools turn up first.
