fix(test): pass anno_scale arg to expand_insert in text_font_rendering

The annotative feature (1b037a6) added a 15th `anno_scale: f32` parameter to `scene::cache::block_cache::expand_insert` and updated the production call sites, but the text_font_rendering integration test was left at 14 arguments, so the test binary fails to compile with E0061 once rebuilt.

Pass `1.0` (no annotative scaling), matching the `BlockCache::build(&doc, 1.0, ...)` call the test already uses.
