Fiona Klute 10088b5381 support/testing: transfer config in environment instead of class variables ...

Passing runtime configuration to tests in BRConfigTest class variables
requires the "fork" start method for multiprocessing. With
"forkserver" (default for POSIX platforms since Python 3.14) class
variables modified in the parent process are lost, because the child
process does not inherit the full Python state. This broke the way
support/testing/run-tests sets configuration for BRConfigTest, so a
start method override was added in commit
3d2141bcee.

Instead this patch adds a settings dataclass (requires Python >= 3.7)
which is serialized into an environment variable from run-tests and
read during BRConfigTest.__init__(). Reading is skipped if the
environment variable is not set so test discovery (not execution)
works without configuration (e.g. utils/get-developers uses this).

With that, run-tests no longer relies on a specific multiprocessing
start method.
