* feat(i18n): translate web console messages in the frontend and AI-client errors in the backend

Chinese text was hard-coded in API messages, stored log content, emails and
server logs, so it reached users of every interface language.

Text is now translated where its reader is:

- Web console APIs return the English source text as message_key with
  message_params, and the web console translates it in all seven languages.
  message keeps the English text for other API callers.
- Errors returned to AI clients, emails and notifications are translated by
  the backend (en, zh-CN, zh-TW) in the language saved on the account, then
  the language of the request's Accept-Language header.
- A reader who states no language still gets the original Chinese text of the
  messages that were Chinese before, word for word. Gateways that use another
  new-api as their upstream match that text, for example to disable a channel
  whose account ran out of quota.
- Usage, top-up and system log content is stored as content_parts (key and
  params) and rendered in the viewer's language. Task fail reasons and refund
  reasons written by the gateway are English keys. Rows written earlier are
  shown as before.
- Server logs are English.

Also:

- The saved interface language zhTW, and zh-HK, zh-MO and zh-Hant, now select
  Traditional Chinese in the backend instead of Simplified Chinese.
- The built-in group descriptions are translated; descriptions an
  administrator saved are shown as written.
- .agents/rules/i18n.md records the conventions. Tests in i18n/ fail on a
  non-English string literal, on a web console message without translations
  and on a locale key without a constant.

* feat(i18n): print server logs in Chinese when LOG_LANGUAGE asks for it

Server log lines are English by default. With LOG_LANGUAGE=zh-CN, the lines
that were Chinese before print their original Chinese text.

common.LogText formats a log line from its English format, which is also the
key of its Chinese text in common/log_text.zh-CN.json. A line without an entry
prints in English. go vet checks the arguments of every call, and
TestServerLogTexts checks that each entry still matches a call and has the
same verbs as its key.

* docs: list LOG_LANGUAGE in the docker compose example

* feat(i18n): translate every server log line and add DEFAULT_LANGUAGE

Every line the gateway prints goes through common.LogText. With
DEFAULT_LANGUAGE=zh-CN, the lines that have a Chinese text in
common/log_text.zh-CN.json print it and the others print English.

DEFAULT_LANGUAGE replaces LOG_LANGUAGE. It also sets the language of
backend messages, emails and notifications for a reader who states no
language: en, zh-CN or zh-TW, English when unset. The list of messages
that stayed Chinese for such readers is removed.

Review fixes:
- Channel test logs store the token name "Model test"; the console shows
  it in the interface language.
- Task fail reasons written by the gateway are fixed sentences the console
  translates. The HTTP status and the upstream detail go to the server log
  when a polled task is failed.
- The auto-disable reason of a slow channel is written in DEFAULT_LANGUAGE.

Also:
- Drop the repository-scanning lint tests, the i18n rules file and its
  read gate. AGENTS.md keeps the conventions in four lines.
- Payment error toasts keep their previous text and only add the
  translated message key.
- Remove guards and helpers that no caller needs.

* fix(i18n): address review on language lookup, notices and error responses

- Relay requests no longer load the user a second time to find the
  language: the settings TokenAuth put into the request are used as they
  are, also when they hold no language.
- Upstream model update notices are rendered in each recipient's saved
  language, DEFAULT_LANGUAGE when none.
- /api/usage/token and /api/log/token answer with backend-translated
  messages again, with the keys and status codes used before this PR.
  Their callers are scripts, not the web console.
- Webhook notifications fill {{value}} placeholders like the other
  senders. Running the rendered text through Sprintf appended
  %!(EXTRA ...) and broke %2F in links.
- RootUserLanguage reads the setting of the root user it already loaded.
- zh_TW and zh_HK are read as Traditional Chinese.
- Add common.ApiErrorStatus for error responses under another HTTP status
  and use it where those responses were built by hand.
- Remove middleware.GetLanguage, which had no callers.
