Adds SignStreamToken / VerifyStreamToken (HMAC-SHA256 over
trackID|exp) and modifies handleGetStream to accept either the
existing session cookie OR a valid signed token. Stream route
moved out of the authed group so the handler's own auth check
runs and the token bypass is reachable.
Enables Sonos / UPnP speakers to fetch the stream URL without
carrying the user's session cookie - they cannot. The token is
short-lived (max 24h per the design); expiry checked at request
time only, not per-byte, so long tracks play through.
streamSecret field on handlers is nil for now; Task 2 wires the
loader (env var with auto-generated fallback persisted in
app_preferences).
Adds auth.OptionalUser - the permissive sibling of RequireUser
that attaches the user to context when a valid cookie / bearer is
present but does NOT 401 on absence. The stream route is wrapped
with it so the handler can fall through to the token path when
no session is present.
newLibraryRouter (test fixture) gets a synthetic-user middleware
on the stream route so existing media_test tests keep passing
without seeding a real session row - production traffic uses
auth.OptionalUser, the test path uses auth.UserCtxKeyForTest().
Five tests cover round-trip, tampered token rejection, expiry,
wrong-track-ID, and wrong-secret rejection. CI verifies.
Deletes the session row keyed by the cookie/bearer token and
clears the cookie on the client. Best-effort DB delete — logout
still succeeds for the client if the row's already gone.

Resolves /api/* callers from session cookie first, Authorization
bearer second. Touches last_seen on success for future active-
sessions UI. Adds GetUserByID query used by the middleware.

Shared primitives for /api/* auth: mint a url-safe opaque token,
hash it for storage, verify a bcrypt password hash.
