Carries the raw ID token in the session cookie so logout can hand it back
to Keycloak as id_token_hint, letting it skip its own logout-confirmation
prompt -- otherwise a user could cancel out of it and land back in the app
with a Keycloak SSO session but no geniusrun profile (e.g. right after
deleting their account).
Lets an external reader (sqlite3 CLI, DB Browser, DataGrip) inspect the
database file concurrently without "database is locked" errors while
geniusrund is running. Doesn't change in-process concurrency -- queries
are already fully serialized via SetMaxOpenConns(1).
auth: fix flaky tampered-cookie tests
Both tests corrupted a signed cookie by blindly overwriting its last
character with "x", which is occasionally a no-op if that character (part
of the token's signature, so effectively randomized by the embedded
timestamp) already happened to be "x" -- silently passing without having
tampered with anything. Confirmed via 15 repeated runs (3 spurious passes)
before the fix and 30 clean runs after. flipLastChar now guarantees the
byte actually changes.
