As the PHP 7.4 image broke with missing security dependencies in Debian Bullseye (at time of writing, as yet unresolved), resolved to complete the upgrade to PHP 8.4 rather than try to build a stopgap solution based on existing PHP 7.4. Unfortunately PHP 8.4 has a number of incompatible changes in 8.x series, documented at https://www.php.net/manual/en/migration80.incompatible.php. I have audited some of the more obvious ones -- but there is potential for other breakages which we will need to monitor. Changes required: * move from PHP 7.4 to PHP 8.4 Docker image (upgrades Debian, Apache, PHP as major components) * update apt process for accessing Microsoft packages on Debian * add libicu-dev and install intl php extension (not included by default in the 8.4 image) * dependency upgrades forced for Sentry, phpunit, curl-client, guzzlehttp/guzzle * removed unused parsedown, parsedown-extra * addition of BCTLS flag to .htaccess mod_rewrite rules (https://stackoverflow.com/q/75684314/1836776) * Add unit tests to verify several endpoints - focus on spaces in parameters where they are allowed (e.g. legacy keyboard ids) * Fixup call to `str_getcsv` * Other minor tweaks as required See-also: keymanapp/keyman.com#828 See-also: keymanapp/s.keyman.com#1712 See-also: keymanapp/keymanweb.com#210 See-also: keymanapp/help.keyman.com#2655 Relates-to: keymanapp/keymanweb.com#209 Test-bot: skip

Uh oh!
