Christophe Vila 0ff6793854 store: enable WAL journal mode
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.
