{#
  Coffee House Flash Messages Component.
  Renders server-side flash messages with proper ARIA roles and dismiss buttons.

  Expected context:
    - flash_messages: list[dict] with .level ("success"|"error"|"warning"|"info") and .message
    - OR: error (str) — shorthand for a single error message (Auth login pattern)
