docs: document usage alert settings

[factory-yuan-xia]

Summary

• document the per-user usage-limit alert preference and org-managed weekly summary control in English and Japanese
• clarify that the per-user preference is stored in the Factory App profile and cannot be configured in settings.json
• add disableWeeklyUsageSummary to the managed-settings schema examples and document active service-account coverage

Validation

• npx -y mint validate
• npx -y mint broken-links
• parsed the English and Japanese JSON examples
• git diff --check and sensitive-data scan

The accessibility checker reports existing repository-wide findings unrelated to these changed lines.

Docs are solid overall, but listing the profile-only disableUsageLimitAlerts alongside settings.json keys is likely to confuse readers, so separating it (or removing it from the table) would improve clarity.
