The risk control center's moderation log records had no field for the
keyword that triggered a keyword block, so the admin UI couldn't show
which keyword was hit (only the application slog logged it).
- migration 156: add matched_keyword column to content_moderation_logs
- ContentModerationLog gains MatchedKeyword; set it on keyword block
- repo CreateLog/ListLogs persist and read the column
- frontend: show "命中关键词" inline in the log table and detail modal
- i18n: add matchedKeyword (zh/en)

When converting a Chat Completions stream into Responses events, the first
tool_call delta chunk was copied wholesale into stream state (including
function.arguments), then the same chunk's arguments were accumulated again by
the shared `+=` block. For OpenAI this is harmless because its first tool_call
chunk carries empty arguments, but upstreams that pack id+name+arguments into a
single chunk (e.g. GLM/Zhipu) end up with doubled arguments such as
{"cmd":"ls"}{"cmd":"ls"}. Codex then fails to parse the tool call with
"trailing characters", breaking every tool invocation.
Reset the copied arguments so the shared accumulator counts them exactly once,
keeping the emitted delta and the final done/arguments consistent.

When gpt-image upstream returns response.completed with no image but a text
refusal (content moderation, e.g. the model replies "this request was judged
unsafe to generate"), the soft-failure path treated it as a probabilistic
upstream failure and returned a retryable UpstreamFailoverError (502). Retrying
or switching accounts is futile for a content-policy block — it just burns
other accounts' quota and still surfaces an opaque 502 to the client.
Distinguish the two no-image cases:
(A) model text refusal -> 400 content_policy_violation, no retry, refusal
reason passed through to the client.
(B) truly empty response -> unchanged: retryable UpstreamFailoverError (502).
Adds extractOpenAIImagesModelRefusal (extracts the refusal text from
output_text.delta / message output_text, capped at 600 chars) and two unit
tests; the existing empty-response retry test is unaffected.
The "[Billing] Using fallback pricing for model: X" warn was emitted on
every request for any model not in LiteLLM but matched by getFallbackPricing
(e.g. "glm-5.2" substring-matches the "glm-5" fallback price). Via the stdlib
log bridge it is inferred as WARN and persisted to ops_system_logs, producing
tens of thousands of rows/day. It fired even when channel pricing already
overrides the price, and from several call sites (resolver, account-stats
pricing, non-channel billing, admin lookup).
Dedup the warn at the source (BillingService.GetModelPricing) via a sync.Map
keyed by the already-lowercased model name, so each model logs at most once
per process while keeping one audit line. Billing amounts are unchanged.
Also clarify the model/mapping pattern conflict error to state that names are
matched case-insensitively, so an existing entry (e.g. "GLM-5.2") already
covers all case variants and the lowercase variant need not be added — the
behavior the issue mistook for a case-sensitivity bug.
