feat(web): optimize family data polling during agent conversation

[Nightbr]

Summary

Optimizes the family data polling to only occur during agent conversation, eliminating continuous background polling when idle.

Changes

apps/web/src/hooks/use-family-data.ts

• Added an isPolling option parameter that controls when polling is active
• When isPolling is true, polls every 1 second (fast enough to catch updates during conversation)
• When isPolling is false (default), polling is completely disabled

apps/web/src/hooks/use-chat.ts

• Added isPolling state that tracks whether polling should be active
• Added triggerPolling() callback that:
  • Enables polling immediately
  • Resets a 5-second timer on each call
  • Automatically disables polling after 5 seconds of no new messages
• Calls triggerPolling() every time a text chunk is received from the agent
• Exposes isPolling in the return value

apps/web/src/components/family/family-panel.tsx

• Accepts new isPolling prop
• Passes it to useFamilyData hook

apps/web/src/App.tsx

• Gets isPolling from useChat()
• Passes it to <FamilyPanel isPolling={isPolling} />

Behavior

• Before: Continuously polled every 5 seconds, even when idle
• After: Only polls for 5 seconds after receiving an agent message, then stops. Timer resets on each new chunk received, ensuring data stays fresh during conversation while not wasting resources when idle.
