Grails 7 - plugin-ui needs updated to latest js dependencies

[jdaugherty]

Issue description

plugin-ui has not been updated to the latest js dependencies. See commits:

• f5e348d - initial work
• 44a17cf - revert after discovering the scope

Also note that there are several existing errors of not being able to find various css/js files without any upgrades. Significant test failures occur (likely due to the bootstrap / datatables upgrades) so the html needs updated to work with the newer dependencies.
