Auto-fix JSON comments and trailing commas for HTTP request bodies

Add a per-request "Automatically Fix JSON" toggle (default: on) that strips
comments and trailing commas before sending HTTP requests. When disabled,
comments are sent as-is and the editor linter flags them as errors.

- New JsonBodyEditor component with settings dropdown and dismissible banner
- Configurable JSON linter (allowComments/allowTrailingCommas) via lintExtension prop
- strip_trailing_commas pass in Rust strip_json_comments pipeline
- Fix JSON formatter pulling standalone comments onto previous comma line
- Add get_bool_map helper, maybe_strip_json_comments, and related tests
