refactor: story titles to Domein/<Context>/<Name>; add 2 missing stories (RD-04)

Three dashboard-section stories used a fourth title segment
(`Domein/Registratie/Dashboard/<Name>`) that the sidebar rule does not have.
Drop the `Dashboard/` segment so all story titles follow the one rule from
CLAUDE.md decision 5.

Add the two missing stories for sections that have more than one visual
state: `wat-moet-ik-regelen` (4 states) and `wat-wilt-u-doen` (2 states, the
first story in the new `Domein/Overzicht/` bucket). `beheer-links` gets no
story — it has one visual state and its other branch renders nothing.

The `MetTaken` story disables the a11y addon with the same reason and WP-11
reference already used on `task-list.stories.ts` and `choice-list.stories.ts`:
`app-choice-link`'s host sits between the keuzelijst `<ul>` and its `<li>`,
a pre-existing structural gap this ticket does not fix.
