fix(providers/qoder): disambiguate OAuth/CLI vs API-key error surface (#2247)

When a Qoder connection lands in OAuth/CLI-flavored mode but the user
has pasted a Personal Access Token, the provider test route surfaces
"Local CLI runtime is not installed" plus a cascading 401 from
DashScope. Neither error tells the user "you picked the wrong auth
mode, switch to API Key".

The runtime check now detects this state (Qoder + non-apikey authType +
a token present on the connection or providerSpecificData) and surfaces
a single actionable message: "Qoder OAuth/Local CLI mode is selected
but the Qoder CLI is not detected. If you have a Personal Access Token,
switch this connection to API Key auth instead."

Non-Qoder providers and Qoder in real OAuth/CLI mode without a token
still get the original generic message.

 - **fix(auth):** accept `x-api-key` header in `extractApiKey` so Anthropic-native clients (Claude Code, `@anthropic-ai/sdk`) hit the same per-key policy enforcement as Bearer clients. Previously these requests were treated as anonymous, bypassing model/budget/rate-limit policies and showing up as `NULL` in `usage_history.api_key_id` (~50% of traffic invisible in Costs/Analytics). `Authorization: Bearer` still wins when both are present (back-compat). (#2225)
 - **fix(translator/claude-to-openai):** stop including `cache_creation_input_tokens` in `prompt_tokens`. Anthropic pads short prompts up to a 1024-token minimum on cache creation, so a 2-token `"hi"` could be reported as ~2008 `prompt_tokens` and inflate downstream billing (Sub2API/NewAPI/OneAPI) ~250x. `prompt_tokens` now matches the dashboard "Total In" (`input + cache_read`); `cache_creation_tokens` is exposed separately in `prompt_tokens_details.cache_creation_tokens` for auditing. (#2215)
 - **fix(ui/claude-extra-usage):** clarify the toggle-success notification text to spell out the toggle→effect relationship ("Claude extra-usage blocking enabled/disabled" instead of the ambiguous "blocked/allowed"). (#2157)
+- **fix(providers/qoder):** disambiguate the "Local CLI runtime is not installed" error when a user pastes a Personal Access Token but the connection is in OAuth/CLI-flavored mode. The test route now surfaces a single actionable message ("switch this connection to API Key auth") instead of cascading CLI + 401 errors. (#2247)
