Arkadiusz Fal 9b5d2b001f Probe before rejecting a credential
Invidious answers a revoked session with 403, not 401, so the failure
reached recordServerOutcome as a plain HTTP error and fell through the
switch: an account whose session died server-side kept reporting
signedIn forever, and credentialRejected was unreachable on the
commonest backend. The roadmap's rule cuts the other way too — a raw
401/403 alone must never reject, because the failure may be about the
operation (someone else's playlist) rather than the login.

recordServerOutcome now treats .unauthorized and HTTP 401/403 alike as
suspicion, not verdict: after the existing basic-auth-proxy exclusion,
it hands the account to a new CredentialProbeService, which re-asks the
server with a harmless authenticated read — Invidious's auth
subscriptions endpoint with the same SID, Piped's subscriptions with
the same token. Only a probe-level 401/403 marks the account
credentialRejected; success means the original failure was
operation-specific and the account stays signedIn; an unreachable
probe records exactly that, and anything ambiguous leaves the status
alone.

The probe applies its verdict only if the account still exists and
still holds the credential it tested — a replacement or an identity
flip mid-flight drops the answer, and a dropped answer starts no
cooldown, so the login the user just fixed is examined without delay.
One probe per account may be in flight; an answered probe stands for a
cooldown before the next suspicion re-asks.

With rejection finally reachable, the existing machinery engages on
its own: the validators fall back to local data, server mutations
pause, and a successful call or re-sign-in lifts the mark.
