Inline filtering results, select-all across pages, country flags, settings RBAC, and inline role changes

- Round detail: add skeleton loading for filtering stats, inline results table
  with expandable rows, pagination, override/reinstate, CSV export, and tooltip
  on AI summaries button (removes need for separate results page)
- Projects: add select-all-across-pages with Gmail-style banner, show country
  flags with tooltip instead of country codes (table + card views), add listAllIds
  backend endpoint
- Settings: allow PROGRAM_ADMIN access to settings page, restrict infrastructure
  tabs (AI, Email, Storage, Security, Webhooks) to SUPER_ADMIN only
- Members: add inline role change via dropdown submenu in user actions, enforce
  role hierarchy (only super admins can modify admin/super-admin roles) in both
  backend and UI
