chore: forget stale Fern Replay patch for #806 (version-bump residue) (#828)

patch-1b45413e was captured from "[Speech Engine] Add disable_auth
parameter (#806)", but its remaining diff is only a hardcoded version
bump (2.55.0 to 2.56.0) plus websockets >=13.0 (now native via the
generator config). Because it pins an old version string, it collided
with the version line on every regeneration and surfaced as an
unresolved conflict (most recently in the v2.60.0 regen PR #826).

Running `fern replay forget patch-1b45413e` drops it from the active
patch set and tombstones its content hash so it is not re-captured.
The #825 multipart fix (patch-560b8934) is unaffected, and disable_auth
itself is generated from the spec and does not depend on this patch.
