Replace the public stored-token row with an initial-token input that carries only token-specific facts. Bind the token to the session and initialize it as unused inside AuthSessionStore so callers cannot create mismatched session/token rows.
Delete the owning auth session inside the refresh-token rotation transaction when a spent token is replayed. Return the replay outcome only after the revocation commits, and propagate database failures without claiming the chain was revoked.
Points the session listing, revocation, refresh, and logout paths at
`AuthSessionStore`. Listing a user's sessions and revoking one stop scanning
the whole refresh-token keyspace; both are now indexed queries.
Fixes two timestamps that were wrong by construction. `created_at` was fed
from the newest token's `issued_at`, so a session's reported start drifted
forward on every refresh, and `last_seen_at` read a field only ever set at
issue -- so both rendered the same value. They now come from the session row,
where they mean what they say.
Deletes `next_refresh_row`, which had to fabricate an identity of
("https://github.com", "0") and empty profile strings for the no-existing-row
case, because a token was required to carry chain-level fields. Rotation now
takes just the new hash, expiry, and user agent. That also removes the
pre-read it existed to feed, closing the window between that read and the
one `consume_and_rotate` did itself.
Opening the store per request is gone with it: five handlers each had a
500-response arm for "could not open the store", which field access on
AppStores cannot fail.
Drops the replay-revocation cache. Its only effect was reporting `revoked`
rather than `expired` for the third and later presentations in a concurrent
burst, and `fabro-client` (client.rs:508-513) matches both codes in one arm
and treats them identically. Replay detection itself is unaffected: it is
`Reused` into `delete_session`, which lives in the database. The concurrency
test now accepts either code, since losers that arrive after the winner's
revocation find the row already cascaded away.
