Part of #7845, #7709.

Checklist: done [c:fd1805c2]

What

Checks the siblings of the container fix: START FROM / RETRIEVE INTO and WRITEQ / READQ TS and TD. #7878 pinned that they translate under zos_comp5; this runs them. test_det_zos_comp5_queue_run_7845.py pushes a text + S9(4) / S9(9) / S9(18) COMP-5 group through the generated runtime sequence (DetCics.toRegion / fromRegion around CicsTask TS, the TD String record, startData for START) with the region page equal to the program's and with cp037.

Result: the values read back are the same in every case. The stored image is IBM's big-endian bytes when the pages are equal, and for TD. With a different region page, the TS item and START data hold the bytes transcoded one by one. No code change: the pages are a run-time property (CobolRecords.charset(), gitgalaxy.cics.charset), so a translate-time refusal would over-refuse, and the values survive. C7.md records the boundary.

Class / Sibling gaps

Class: zos_comp5 byte stores where the runtime holds program bytes (SQLCA, COMMAREA, containers done in #7841 / #7865 / #7868 / #7933; this PR: START / RETRIEVE, TS, TD checked and run).
Sibling gaps:

• Comparator reversal of queue / START bytes (comp5_byte_order has container_layouts for containers only). Status: missing. No burned program needs it (SEQPNT, ASYNCPNT, PAUDBLOD, PAUDBUNL, DBUNLDGS issue no START / RETRIEVE / WRITEQ / READQ). Scope: sweep, only if a burned program comes to need it.
• TS / START stored image transcoded under a differing region page: frontier, no burned program.
• Foreign CALL, CEE* / DSNTIAC: refused by design (LE / Db2 runtime reads COMP-5 little-endian).
• Re-survey of the 3 census programs ([c:884b987d]): census clones, tool-counted, not here.

Facts checked: the five comp5_byte_order burned cases hold no START / RETRIEVE / WRITEQ / READQ; audit_check.py clear; new test and the container tests pass (det extras installed).
