Fix email links broken in Outlook and standardize all email URLs

- Rewrite ctaButton to use td-background pattern (works in all clients
  including Outlook, Gmail, Yahoo, Apple Mail) instead of VML/conditional
  comments that broke link clicking in Outlook desktop
- Add plaintext fallback URL below every CTA button so users always have
  a working link even if the button fails
- Add getBaseUrl() and ensureAbsoluteUrl() helpers in email.ts to
  guarantee all email links are absolute https:// URLs
- Apply ensureAbsoluteUrl safety net in sendStyledNotificationEmail and
  sendNotificationEmail so relative paths can never reach email templates
- Standardize all NEXTAUTH_URL fallbacks to https://portal.monaco-opc.com
  (was inconsistently http://localhost:3000 or https://monaco-opc.com)
- Fix legacy notification.ts: wrong argument order in
  sendJuryInvitationEmail (URL was passed as name parameter)
- Fix legacy notification.ts: missing NEXTAUTH_URL fallback for
  evaluation reminder URL construction
- Change tooltip styling from red bg to white bg with black text
