fix: a second click on Add while the lookup waits tracks the token once (closes #727)

The "already tracked" check ran only before the contract lookup, so a second click while the first lookup waited tracked the token twice. AddToken and SettingsAddToken now check again when the lookup answers. An answer for a token tracked meanwhile shows the "already tracked" flash message and tracks nothing. Model: opus-5-5
