Clean up unused state and logic in IntentMultiEventHomeScreen

- Remove unused `localAccount` and `appName` state variables along with their corresponding `LaunchedEffect` blocks that were fetching application names from the database and cache.
- Remove several unused imports, including `ApplicationNameCache` and `AmberUtils`.
