feat: add account_id override to POST /api/notifications

[sweetmantech]

Summary

• Add optional account_id body param so org API keys can send notifications on behalf of member accounts
• Refactor validateCreateNotificationBody to handle auth + body parsing (matches artists pattern)
• Simplify createNotificationHandler to delegate to the new validate function
• Add tests for account_id override, auth passthrough, and 403 access denied

Test plan

• 18/18 notification tests pass (pnpm test lib/notifications/)
• Verify pnpm build passes in CI
