fix(ui): update suggestions

[pwltr]

Changes

• simplify todos
• adds a workaround for <Dialog />s getting stuck on iOS

Notes

• initialize state with a simple array of all todos
• if user dismisses a todo, remove the item from the state
• if user completes a todo, remove the item from the state
• predefined todos are added on user action (lightningSettingUp)
• depending on other state, decide what to do when user clicks todo card

The workaround for the Dialog will issue a warning but it works. Will be removed as soon as the upstream issue gets fixed or after we upgrade react-native which enables us to swap the Dialog for the native Alert.
