fix: repair defects surfaced by gating CI on lint and typecheck

`npm run check` reported 15 errors and `npm run lint` 20, all pre-existing, so
neither gate could pass. Fixing them turned up three real bugs:

- SignOut destructured `{ error }` off `.then(() => {})`, which resolves to
  undefined, so every sign-out threw a TypeError - after the signed-out event had
  already been emitted. Sign-out also left the user on the protected page they
  were on, still showing its content; it now returns them to the home page and
  re-runs the server loads.

- SignUp passed `redirectTo`, which is not a signUp option and was silently
  ignored, so the confirmation link has always used Supabase's configured site
  URL. Documented rather than changed, since pointing it elsewhere needs an
  absolute allow-listed URL.

- The Pokédex page tracked totalRecordsCreated but never passed it to the box
  view, so the "Processed N entries so far" progress message never rendered.

The rest is typing and dead code: cookie callback parameters in hooks.server.ts
and +layout.ts, the untyped supabase props, a query-builder type that made
PostgREST rows untyped downstream, an unused session destructure, and
`while (true)` paging loops rewritten as `for (;;)`.
