Delete a font file

Removes this font's typeface and deletes the stored file, returning a receipt naming what was removed and the font as it now stands. Requires `customisers:write` and an `Idempotency-Key`. This stops the font rendering. A file-less font is a state the merchant admin allows and the storefront understands, but a shopper who selects a font whose file cannot be loaded gets a sign that will not add to cart. `font_file.has_font_file` comes back false, which is the signal to either upload a replacement or stop offering the font. Deleting a font that has no file answers 404. The delete clears the customiser's cached storefront configuration and runs the advisory language sync, and never regenerates Shopify products, product images, or the product cache.
