## What kind of change does this PR introduce?
Refactor
## What is the current behavior?
`/incident-status` is handled via Pages Router.
## What is the new behavior?
`/incident-status` is handled via App Router, enabling use of Vercel
Data Cache to cache the upstream fetch.
## Additional context
Adding the first App Router route handler triggered `next typegen` (run
as `pretypecheck`) to generate `.next/dev/types/validator.ts`, which
imports all route files and expanded the type-checked graph. This
surfaced pre-existing `null`-safety errors in:
- `components/grid/SupabaseGrid.utils.ts` — `useSearchParams()` result
- `components/layouts/ProjectLayout/UpgradingState/index.tsx` —
`useSearchParams()` result
- `pages/project/[ref]/sql/quickstarts.tsx` — `useParams()` result
- `pages/project/[ref]/sql/templates.tsx` — `useParams()` result
These are fixed with optional chaining. The `tsconfig.json` change
(adding `.next/dev/types/**/*.ts` to `include`) is auto-generated by
Next.js and committed as correct behavior.
