feat(status): add pr draft, issue resolved, and --reason for issue close

Add `ngit pr draft <id>` to convert a PR back to draft (kind-1632).

Add `ngit issue resolved <id> [--reason <text>]` to mark an issue as
fixed (kind-1631 GitStatusApplied), distinct from close which signals
wontfix/duplicate/invalid.

Add `--reason <text>` to `ngit issue close` — stored in event content.

Also fix success/error message wording in pr_status and issue_status to
use consistent past-tense action strings.
