feat(usage): add official subscription quota template with unified tier rendering

Changes:
- Add official_subscription template type for Claude/Codex/Gemini
- Replace implicit 'category=official auto-query' with explicit opt-in template
- Default disabled; users enable via usage script modal with configurable interval
- Unify tier→label mapping across subscription and script paths via labeled_tier_parts()
- Fix tray rendering: week aliases (seven_day/opus/sonnet) now use highest utilization
- Add depth guard: official_subscription checks enabled flag in query_provider_usage_inner
- Add cache invalidation symmetry: invalidate_subscription() for disabled providers
- i18n: add templateOfficialSubscription + hint in zh/en/ja/zh-TW

Backend (Rust):
- provider.rs: add TEMPLATE_TYPE_OFFICIAL_SUBSCRIPTION branch, flatten SubscriptionQuota→UsageData
- tray.rs: extract labeled_tier_parts() shared by both summary functions, use max_by for multi-alias groups
- usage_cache.rs: add invalidate_subscription() method
- Test coverage: add week-alias highest-utilization tests for both paths

Frontend (TypeScript):
- UsageScriptModal: add official_subscription to templates, auto-detect for official providers
- ProviderCard: gate useUsageQuery with !isOfficialSubscriptionUsage, pass autoQueryInterval to footer
- SubscriptionQuotaFooter: accept autoQueryInterval prop, default 0 (disabled)
- constants.ts: add TEMPLATE_TYPES.OFFICIAL_SUBSCRIPTION

Fixes tier rendering regression where:
- Claude/Codex: seven_day was missed (only weekly_limit matched) → lost 7-day window in tray
- Gemini: gemini_pro/flash/flash_lite fell through to fallback → leaked machine names
- Multi-window (opus+sonnet): find() took first, not worst → underestimated utilization and emoji color

All tests pass (cargo test + cargo clippy clean).
