fix(lsp): silence clippy too_many_arguments on render_page_html

Adding list_margin pushed render_page_html to 8 params, tripping
clippy::too_many_arguments under -D warnings in CI. Every parameter is a
distinct render input and the function has a single production caller, so
scope an #[allow] rather than introduce an options-struct abstraction.
