fix(core): the last fixes' core half (W1 W2 W5 W19)

Stage 4 of docs/modules/rust/PLAN_LAST_FIXES.md, with the org lead's
2026-10-22 decisions.

W19: one module per site at boot, as at install. The first module
directory by name holds the site, whether or not it then loads; every
other is recorded startup_failed at the manifest stage, before a line of
its code is required, with a reason naming the module that holds the
site. Module-uo and Module-Rust side by side used to fail the second
with a slot collision. Loader, lifecycle, schema and event-contract
tests that loaded several fixture modules now load each case alone.

W1: a reconcile files a resource the game no longer has, and that is
past its `until`, as expired rather than orphaned, with the same log
line expired() writes. No MODULE_API bump: `until` and reconcile's
answer are unchanged.

W5: a dry run that passes on the draft is kept with the fingerprint of
the validated spec (three nullable columns on event_definitions).
Publish stamps the new version verified, with that dry run's reviewer
and time, when the spec it freezes has the same fingerprint, and writes
version.verified on the occurrences it re-pins. Verify answers
draftRecorded and publish answers verified; OpenAPI regenerated.

W2: the run console says "Phase p1: steps done, waiting to advance" and
"Why this phase has not advanced", not "has not started".
