[mCBM 2024] Fixes to TOF mapping (BMon and test det), legacy and online

Fixes taken from NH lustre folder after he indicated it was needed, hopefully without missing anything

This should fix the mapping for 2 of the new modules + include a small fix to the number of boxes for the legacy mode

@v.friese please do not hesitate to merge without waiting for me if @n.herrmann approves it, it is probably required if we want to switch later in the WE to .rra only
