PHP 8.3 Support

This time we're a little ahead for once. PHP 8.3 is due in a week, and we are compatible with it now! There's not much else to say about it, so let's continue with the fixes.

• Support for PHP 8.3 #​5136

Fixes

You may have noticed a dashboard endlessly loading in the morning after you got to work again. The web server may also have stopped that with a complaint about a too long URL. This is now fixed and the dashboard should appear as usual. Then there was an issue with our support for PostgreSQL. We learned it the hard way to avoid such already in the past again and again. Though, this one slipped through our thorough testing and prevented some from successfully migrating the database schema. It's fixed now. Another fixed issue, is that the UI looks somewhat skewed if you have CSP enabled and logged out and in again.

• Login Redirect Loop #​5133
• UI database migration not fully compatible with PostgreSQL #​5129
• Missing styles when logging out and in while CSP is enabled #​5126
