fix(mothership): catch draft restore errors instead of crashing /home

Wrap the mount-time draft restore in try/catch with clearDraft on
throw, and coerce text to a string in the useState initializer.
A corrupt entry in mothership-drafts:v1 localStorage previously took
down the entire workspace via the error boundary.
