style: fix missed Phase 1/2 items — FA→Lucide, a11y, variant-* cleanup

- +layout.svelte: replace fa-cog/fa-spinner spinners with LoaderCircle;
  variant-filled-primary → preset-filled-primary on reload button
- events/+page.svelte: fa-calendar-alt → CalendarDays, fa-exclamation-triangle
  → TriangleAlert (+ text-red-500 → text-error-500), fa-spinner → LoaderCircle
- sign_in_out.svelte: fa-times → X, fa-sign-in-alt → LogIn
- journals/+layout.svelte: fa-arrow-right → ArrowRight
- journal_entry_header.svelte: fix focus:ring-0 → focus:ring-2 focus:ring-primary-500
  (WCAG 2.1 AA — removes keyboard focus indicator violation)
