Spring security updates

Spring Boot 4.x compatible Spring Security

I added the ability to skip forcing all tasks to run as part of this PR, i.e.

         DO_NOT_CACHE_TESTS=1 ./gradlew check 

This will run all tests but use the cached versions of other tasks.

@jamesfredley @matrei looks like all of the spring security tests are working in 8.0.x again so I think we can merge.

No, the suggestion isn’t fully correct — using ?.toBoolean() results in null when the environment variable is unset, which will cause a runtime error in boolean expressions like !doNotCacheTests, whereas the current 'as Boolean' cast safely defaults to false.

If the variable is typed as boolean, null will be coerced to false. Using toBoolean() will properly parse input values: '1', 'true', 'y' etc. to true.
