fix: prevent silent save failure in admin settings form

fix(apicompat): support array content for system and tool messages

The settings form contains multiple <input type="url"> fields that lack
a name attribute. When a field value fails browser URL validation, the
browser silently blocks form submission without showing an error — no
network request is made, and the user sees no feedback.

Root cause: HTML5 form validation requires a focusable element with a
name attribute to surface errors. Without it, validation fails silently.

Fix:
- Add novalidate to the <form> to disable browser-native URL validation
- Add an isValidHttpUrl() helper in saveSettings() to replicate the
  same checks the backend performs
- Optional URL fields (frontend_url, doc_url): auto-clear invalid values
  instead of blocking the save, matching backend behaviour (these fields
  accept empty string without error)
- purchase_subscription_url: block save with a clear error message when
  enabled + invalid; auto-clear when disabled to prevent the backend 400
  "Purchase Subscription URL must be an absolute http(s) URL" error

LegacyPrintf uses inferStdLogLevel() to infer log level from message
text. Any message containing the word "error" is classified as ERROR
level, causing the entire signature-retry recovery flow (which succeeds)
to produce spurious ERROR log entries.

Changes:
- Remove noisy [SignatureCheck] debug logs inside isThinkingBlockSignatureError
  that were logging every detected signature check as ERROR
- Change retry-start log to WARN level via [warn] prefix
- Change retry-success log to INFO level by removing "error" from message

1. Start() 中 wg.Add(1) 从 run() goroutine 内部移到 go s.run() 之前，
   防止 Stop().wg.Wait() 在 Add 之前返回导致孤儿 goroutine。
2. tryAcquireLeaderLock 返回的 release 闭包改用独立的
   context.Background()+5s 超时，避免捕获的 evaluateOnce ctx
   在 defer 执行时已过期导致锁释放失败（最长阻塞 90s TTL）。

feat(openai): 增加 gpt-5.4-mini/nano 模型支持与定价配置

fix: quota display shows stale cumulative usage after daily/weekly reset

fix: 修复 OpenAI 转发路径未应用分组默认模型映射

fix(apicompat): 修正 Anthropic→OpenAI 推理级别映射

旧映射错误地将所有级别上移一档（medium→high, high→xhigh），
导致 effort=max 被原样透传到 OpenAI 上游并返回 400 错误。

根据两边官方 API 定义对齐：
- Anthropic: low, medium, high（默认）, max
- OpenAI:    low, medium, high（默认）, xhigh

新的 1:1 映射：low→low, medium→medium, high→high, max→xhigh

The quota reset mechanism is lazy — quota_daily_used/quota_weekly_used
in the database are only reset on the next IncrementQuotaUsed call.
The scheduling layer (IsQuotaExceeded) correctly checks period expiry
before enforcing limits, so the account remains usable. However, the
API response mapper reads the raw DB value without checking expiry,
causing the frontend to display cumulative usage (e.g. 110%) even
after the reset period has passed.

Add IsDailyQuotaPeriodExpired/IsWeeklyQuotaPeriodExpired methods and
use them in the mapper to return used=0 when the period has expired.

- 接入 gpt-5.4-mini/nano 模型识别与规范化，补充默认模型列表
- 增加 gpt-5.4-mini/nano 输入/缓存命中/输出价格与计费兜底逻辑
- 同步前端模型白名单与 OpenCode 配置
- 补充 service tier(priority/flex) 计费回归测试
