fix: browser tab title should always just say "Epicure"

Root layout used title.template ("%s | Epicure") and 38 pages set
their own title, producing "Recipes | Epicure", "Messages — Epicure",
etc. Drop the template, set a flat "Epicure" default, and clear every
page's title override so they all inherit it.
