Subject: [PATCH 1/2] feat(billing-probe): extend upstream billing probe to all
 API-key platforms

/v1/sub2api/billing is a key-scoped sub2api convention: any API-key
account whose base_url points at a sub2api-compatible upstream answers
it regardless of the account platform. Widen probe eligibility from
platform=openai to every API-key account (OAuth/Bedrock stay excluded:
no static key to present).

- central predicate exported as IsUpstreamBillingProbeIdentity; runner,
  manual probe, SetAccountEnabled, admin create/update/bulk validation
  and CRS reconcile all follow it
- probe target resolution reads credentials.api_key/base_url directly.
  OpenAI keeps its official-default base URL and openai transport
  profile. Other platforms whose base_url is empty or points at an
  official provider API domain (anthropic.com, googleapis.com, x.ai,
  grok.com, openai.com - matched on the normalized hostname, port and
  trailing dot stripped, as the exact host or any subdomain) persist
  "unsupported" without sending a request: the create form fills empty
  base_url with official defaults and offers official regional presets
  (e.g. us-east-1.api.x.ai), and official APIs cannot answer
  /v1/sub2api/billing, so probing would only send the account key to a
  nonexistent official path
- due-scan SQL, BulkUpdate probe WHERE, UpdateCredentials stale-snapshot
  CASE and proxy-change invalidation drop their platform filters
  (type='apikey' retained)
- frontend: rate cell, edit/create/bulk modals gate on type==='apikey';
  the antigravity upstream create flow (its own helper and form section)
  shows the auto-probe toggle and passes upstream_billing_probe_enabled;
  bulk WS-mode section stays OpenAI-only; settings copy de-scoped
- tests: multiplatform service unit tests (relay success, official/empty
  base_url unsupported without request, normalized official-host matrix,
  OpenAI defaults preserved), real-PostgreSQL due-scan coverage for
  openai/anthropic/grok plus oauth/disabled exclusion, updated
  sqlmock/CRS/frontend specs; probe stays opt-in per account

#4896 把上游计费探测从 OpenAI API-key 放宽到全部 API-key 账号后，
遗留了四处需要收口的问题：

- M1 官方域抑制清单补 ollama.com。Ollama Cloud 是本仓一等支持配置
  （platform openai/anthropic + type apikey + base_url
  https://ollama.com/v1），放宽后 anthropic 侧这类账号会每个探测周期
  拿 Ollama Key 请求 ollama.com/v1/sub2api/billing 并恒定落空，正是该
  守卫注释声明要防的行为。后缀匹配已覆盖 www.ollama.com 等子域，
  notollama.com 等形似域不受影响。
- M2 legacy 低倍率优先排序补平台门控。newOpenAILegacyUpstreamRateOrder
  遍历全部候选且无平台门控，与 openAIUpstreamCostFactors 的门控不对称；
  放宽后 grok 账号的上游自报倍率开始影响 legacy 调度排序，而实际结算走
  本地倍率，中转方自报低价即可吸流量。现补上同一道门控，使调度侧信任面
  回到 PR 前状态（探测资格的放宽保持不变）。
- L1 修正 IsUpstreamBillingProbeIdentity 注释。原注释称类型限制的依据是
  "OAuth/Bedrock 没有静态 API key"，但 AccountTypeUpstream（antigravity
  中转账号）同样是 base_url + 静态 api_key 却也被排除。仅改注释如实说明
  取舍，不改行为。
- L2 批量探测空选文案去掉 OpenAI 限定（en/zh 成对）。
- L3 unsupported 状态改用加长退避（interval 的 8 倍，仍按 24h 封顶）。
  放宽后大量官方域账号会落 unsupported 并按常规 interval 重排，占满每周期
  20 个名额，把真正接入 sub2api 的中转账号挤到后面。封顶保证上游后来接入时
  最迟一天内会被重新发现；Retry-After 更长时原样保留不被缩短；手动探测不受
  退避影响。

测试：ollama.com 官方域行为级与 host 匹配矩阵用例、legacy 排序平台门控
（含混合候选集）用例、unsupported 退避上下界与 runner 跳过/手动探测放行
用例；同步更新既有 unsupported 的 next_probe_at 断言。
