Suggestions table is missing some indexes.
Index on biblionumber will speed up C4::Suggestions::GetSuggestionInfoFromBiblionumber(), often called in a loop.
Index on status and branchcode will speed up many queries.
Note that an index on budgetid is automatically added by the creation of the foreign key constraint.
Test plan :
- Check performance with an invoice containing a lot of orders.
- Check suggestions pages are faster or at least not slower.
