[Browser Run][/json endpoint] Fix failing curl examples

[blackmountainb]

Summary

Fixes broken curl examples on the /json endpoint page and aligns the request payload shape with what the API actually accepts, so users can copy-paste the snippets and have them run successfully.
Changes:

• Fixed invalid response_format field name.
• Fixed the "With only a JSON schema" curl example. The -d payload was not valid JSON — it opened with a bare "response_format": key and no wrapping {}, and was missing the required url field. Rewrote it as a complete, runnable request body.
• Fixed the missing closing quote in the "Using a custom model (BYO API Key)" curl example (} → }'), which previously caused the shell to hang waiting for input.
• Fixed the "With only a prompt" sample response. The json output block was missing its opening {.
• Standardized curl syntax across all examples to match other quick-action pages: short flags (-X, -H, -d) instead of long flags (--request, --header, --data), and / placeholders instead of CF_ACCOUNT_ID / CF_API_TOKEN.
