Should we move the validation of maxSequencesPerEntry from the backend to prepro #6165
Description
Currently we validate that a sequence does not have more than the allowed number of sequences per entry in the backend, if this validation fails the full submission fails not just that sequence - ideally we would do this on a segment level in prepro.
Does anything speak against this and we shoudl keep this validation in the backend?
This came up as an issue in ingest, I need to validate that I dont submit anything with too many sequences or else other valid entries may fail if they are uploaded at the same time.
