feat(job-array-one-based-index): idgen allocates ordinary IDs only (task 9.1)

Browse source 
idgen() now accepts only a size of 1 (anything else: -EINVAL, context
unchanged) and refuses an exhausted 20-bit sequence with -EOVERFLOW
instead of spilling into the timestamp (also after idgen_array has
taken the last block). Arrays come only from idgen_array; every caller
of idgen/GenerateJobID passes 1. The old multi-element test loop moves
to idgen_array with 1-based assertions.

- [x] 9.1 Restrict ordinary ID allocation to single jobs
- Remove the multi-element path from ordinary ID allocation now that the harness and the API server use the array allocator
- Migrate the existing ID-allocation test loop that requests sizes above 1 to the array allocator
- Done when the old multi-element test loop is gone or migrated, ordinary allocation with size 2 returns invalid-argument in the libxce suite, and the harness and API server builds and suites still pass
