jfjoch_broker keeps FFT indexers and cuFFT plans for its life, not the rotation receiver

The two never-destroyed FFTIndexerReuse and FFTPlanReuse objects move from the
JFJochReceiverRugnuxRotation constructor into the broker's main. In the broker nothing changes.
In jfjoch_test the first rotation receiver no longer keeps indexers and plans for the rest of the
process: with Catch2's random order, the GPU memory tests that ran after one found 37 plans kept and
the indexer memory already taken (CudaFFTPlan_SharedAndKept, IndexerThreadPool_ReleaseIndexersGivesTheCardBack,
IndexerThreadPool_FFTIndexerKeptAcrossPools, the three CI failures on 0d26ecd13).
