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.
