Pre-merge review of the P0 branch:
- Open redirect: login redirected to an unvalidated ?next param, so a crafted
/login?next=https://evil (or //evil) bounced off-site after login. Now only
same-origin relative paths are honored (else fall back to "/").
- Remove the unused useRouter import/binding in the login form.
- Memoize expectedToken() keyed on (password, secret) so middleware stops
recomputing an HMAC on every gated request.
Deferred (low-value/latent, noted): Soulseek cover.jpg isn't retrieved into
staging (UI still shows Cover Art Archive art); _retrieve's basename-keyed map
could undercount same-named files but source_refs come from a single slskd dir;
SignOut visibility rides a server-env read (cosmetic).
web 138 tests green, tsc + build clean.
