f3s/ychat: bump image to b8faffb (fix SQLite corruption over NFS)

Image 67babb2 used PRAGMA journal_mode=WAL, which silently lost writes
on the NFS-backed hostPath PV (WAL needs shared-memory mmap of a -shm
file that network filesystems don't support reliably) -- a registered
user could not log back in because the INSERT never actually landed.
b8faffb switches to the default rollback journal, which only needs
ordinary byte-range locks that NFS handles correctly. The stale,
partially-corrupted ychat.db/-wal/-shm files on the PV were wiped
before this rollout so the pod starts from a clean, empty database.
