Subject: [PATCH 1/2] fix(expo): clear JWT from SecureStore on sign-out to
 prevent stale session errors

When signing out via native components (AuthView, UserButton), the JWT
in SecureStore was not cleared. On the next sign-in attempt, the stale
JWT caused 'session_exists' / 'already signed in' errors because FAPI
still saw the old session. Now explicitly deletes the JWT before calling
clerk.signOut() in both the ClerkProvider native auth sync and the
UserButton sign-out flow.
