Rename analytics event and track proceed without account

Rename the analytics event "user_signed_up" to "sign_up" to standardize naming. Also add tracking for users who choose to proceed without creating an account by emitting a "proceed_without_account" analytics event when they click the corresponding button. These changes ensure sign-up and opt-out flows are both recorded for analytics.
