feat: round finalization with ranking-based outcomes + award pool notifications

- processRoundClose EVALUATION uses ranking scores + advanceMode config
  (threshold vs count) to auto-set proposedOutcome instead of defaulting all to PASSED
- Advancement emails generate invite tokens for passwordless users with
  "Create Your Account" CTA; rejection emails have no link
- Finalization UI shows account stats (invite vs dashboard link counts)
- Fixed getFinalizationSummary ranking query (was using non-existent rankingsJson)
- New award pool notification system: getAwardSelectionNotificationTemplate email,
  notifyEligibleProjects mutation with invite token generation,
  "Notify Pool" button on award detail page with custom message dialog
