Subject: [PATCH] feat: add @Preview composables to EventSyncScreen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

One ThemeComparisonColumn preview per card — renders both dark and light
themes stacked — covering all independently previewable composables:

  SyncProgressCardPreview  — mid-sync progress (312/1024 relays, 4821 sent)
  PausedCardPreview        — paused state with relay/event counts
  DoneCardPreview          — completed run (18K events, 187s)
  ErrorCardPreview         — configuration error message
  ActiveRelaysCardPreview  — 5-relay FlowRow with pulsing chips
  DestinationRelaysCardPreview — all three sections (outbox/inbox/DM)
  ActivityLogCardPreview   — mixed log: found events + empty/unreachable
