style(lms): синхронизировать типографику со шкалой ДС-2 (+2px)

Переопределены токены шкалы Tailwind (--text-xs…--text-5xl) на +2px,
базовый размер body 18px, размеры компонентных классов (.btn-aubade,
.tag-aubade, .admin-sidebar-nav-link) и инлайновые fontSize приведены
к канону дизайн-системы ДС-2. Rem-база (html 16px) не тронута —
спейсинг и сетка не затронуты, растёт только текст.
