Cap free tier to 7 days

[xaelophone]

Summary

• Free users were getting 10 messages/day indefinitely — effectively 300/month, the same as Pro ($15/mo)
• Free tier now expires 7 days after account creation. After that, users are fully blocked and must upgrade
• Applied retroactively to all existing free accounts

Changes

• server/src/lib/limits.ts — Added FREE_TIER_DAYS = 7
• server/src/middleware/usageGate.ts — Free users older than 7 days get 429 with FREE_EXPIRED before daily count is checked
• server/src/routes/usage.ts — Returns freeExpired and freeExpiresAt in usage response
• packages/api/src/billing.ts — Added freeExpired and freeExpiresAt to UsageInfo type
• apps/web/src/pages/FocusPage/FocusChatWindow.jsx — Shows "Your 7-day free trial has ended" message for expired free users

Test plan

• New free user can send up to 10 messages/day for 7 days
• Free user after 7 days gets blocked with upgrade prompt
• GET /api/usage/current returns freeExpired: true, remaining: 0 for expired free users
• Pro and trial users are completely unaffected
