test(secrets): serialize env-var-mutating test classes into one xunit collection

Environment.SetEnvironmentVariable/GetEnvironmentVariable mutate the process-wide environ; concurrent setenv/getenv across parallel xunit test classes is a documented crash/flake source on glibc even with unique variable names. Group the six classes that touch process env vars into a DisableParallelization=true collection so they run serially against each other while everything else keeps running in parallel.
