fix: correct ticket charge API body, logout type, and login/logout flow

- Fix upsertUserChargeLog: use separate userCharge + userChargelog objects
  matching Lionheart reference, validDate 90 days at 4AM
- Fix userLogout: use LogoutType.Logout = 1 (was incorrectly changed to 0)
- Fix loginDateTime tracking: userLoginFull now returns the exact timestamp
  sent to server, ensuring logout uses matching value
- Fix home page logout: call UserLogoutApi before navigating back
- Add force-logout for stale sessions before ticket flow login
- Add comprehensive debug logging across entire ticket flow
