style(ui): pull off-scale spacing and micro-labels onto the scale

Sweep the spacing rests that sat off the 1/1.5/2/3/4/6/8/10 scale: the
health-score panels and their skeleton, the recommendation ask-Coach
gutter, the onboarding tour footer, the vaccination row, the danger-zone
alert margins, the recovery-codes action wrapper, and the chart-tooltip
tile. Move the last hand-written micro-sizes (coach counters, the
personal-record badge, the score-ring label, the dose-history and
cycle-calendar headers, the mood tag chips) onto the text-2xs token, and
give the documents upload buttons the mobile tap floor their peers set.
