Drops dead `id` props and `scroll-mt-28` classes from admin section
components (load-bearing in v1.4 monolithic admin, dead since the v1.5
phase-4b dynamic-route split). Also removes the unused
`LEGACY_ANCHOR_TO_SLUG` map, the `admin-shell` re-export shim, the
`BERLIN_TZ` and duplicate `MS_PER_DAY` constants, the verbose
`AdminSectionPage` docstring, the `useEffect` paraphrase comment in
`ai-section`, and rewrites the `_exhaustive: never` exhaustiveness
guard to the modern `slug satisfies never` form. `UserManagementSection`
now reads `currentUserId` via `useAuth()` instead of accepting it as a
prop.
Findings 1, 2, 3, 4, 6, 7, 8, 11, 15, 16, 17 from
.planning/phase-6-simplify-findings.md.

* `status-card-grid.test.tsx` — replaces the v1.4.6 anchor-id allowlist
with a route-existence check: every card's href must match `/admin/
<slug>` AND `slug` must be in the `ADMIN_SECTION_SLUGS` source-of-
truth, AND `src/app/admin/[section]/page.tsx` must exist on disk.
This guarantees the dynamic-route file can never be silently moved
out from under the cards.
* `sections.test.tsx` — SSR smoke test for every section component
reachable from the dynamic-route renderer. Every section paints a
recognizable heading, and the `<UserManagementSection>` filter pills
+ `<BackupsSection>` "Backup now" button are asserted so the v1.5
fold-ins for T2.6 and T2.7 don't regress silently.
Locale parity for the new admin.section.* keys is enforced by the
existing `i18n-locale-integrity` test suite.
