feat: multi-role jury fix, country flags, applicant deadline banner, timeline

- Fix project list returning empty for users with both SUPER_ADMIN and
  JURY_MEMBER roles (jury filter now skips admins) in project, assignment,
  and evaluation routers
- Add CountryDisplay component showing flag emoji + name everywhere
  country is displayed (admin, observer, jury, mentor views — 17 files)
- Add countdown deadline banner on applicant dashboard for INTAKE,
  SUBMISSION, and MENTORING rounds with live timer
- Remove quick action buttons from applicant dashboard
- Fix competition timeline sidebar: green dots/connectors only up to
  current round, yellow dot for current round, red connector into
  rejected round, grey after
