fix(ci): clear the gate regressions the second merge introduced

The merge with the moved base pushed three budget gates over their ceilings.

credential_hydration collected the per-credential field lookups with a list
comprehension over an async call, which LIT002 reads as building a mutable
value by accumulation. Replaced with asyncio.gather plus chain.from_iterable,
so the lookups now also run concurrently instead of one after another.

The credential form helper test carried an inline object literal that put
no-large-inline-object-arg one over its 560 ceiling. Hoisted it to a named
const.

Two patch sites in the pass-through relay test were counted by TQ008. Both
are genuine boundaries, the http client the test asserts bytes against and
the logging hook that would otherwise want a database, so they carry
suppressions naming the reason rather than being restructured.
