Todoist integration now requires due dates to sync Tasks

Major update for our Todoist users - due dates are now required on Todoist items before they will sync to a Reclaim Task!

After talking with hundreds of beta users, we made this decision for two reasons:

1. First, Reclaim's support for Tasks with no due date is on the horizon, but not here. To accommodate that gap, we've had to silently choose a Task due date for your synced Todoist items which don't have one. That allows Tasks to be scheduled by Reclaim, but not in a way that that's transparent. We'd rather directly expose the requirements of the current product rather than do something confusing.

2. Second, it's currently easy to select all your Todoist projects in the integration settings, choose "All Tasks", and flood yourself with synced Todoist items. By limiting the sync to items where you actually care when they get done, we'll mitigate that scenario while choosing the Todoist items that are a better fit for syncing to Reclaim in the first place.

Optional due dates on Reclaim Tasks are something we're working on, so once that lands, we may revisit this requirement - perhaps just making it a setting.
