refactor: migrate the 3 wizards to the effect map and Primary (RD-08)

The three wizards paired a dispatch with a hand-written effect call
(onPrimary/onRetry + runIfSubmitting/runIfIndienen). A missed call failed
silently. RD-05 added the effect map and RD-07 added the Primary message;
this ticket moves each wizard onto both.

Each wizard now registers its submit effect on createStore, keyed by its
own submitting tag (Submitting for herregistratie and intake, Indienen for
registratie — the type catches a wrong key at compile time). The optimistic
begin/confirm/rollback calls stay inside the effect body, unchanged. The
template dispatches Primary and Retry directly, matching how Back already
worked. onPrimary, onRetry, and runIfSubmitting/runIfIndienen are deleted
from all three components.

herregistratie-wizard drops under the 250-rule-line budget, so its
eslint-disable max-lines header is removed in this same commit (RD-02's
self-cleaning mechanism). intake-wizard and registratie-wizard stay over
budget and keep theirs, both already flagged for RD-22/RD-23.

Three doc comments (in the three machine files, plus one in store.ts) named
the deleted onPrimary()/runIfSubmitting() identifiers in prose. Reworded
them so the "idiom is gone from the repo" grep check is not defeated by its
own explanatory comments.
