Polish up Done Button UI States

Summary:
Improves the UI quite a bit.

• dashed borders everywhere to denote Unsubmitted
• $sky sprinkled everywhere to denote Done
• Consilidate inline-state-is-draft to simply styles.

Test Plan:
Sent myself test comments, logged out, read comments on new account. Marked as done, submitted.
