fix(a11y): name every control by the text it shows

axe 4.14 checks WCAG 2.5.3 (label in name), and the app frame failed it
on every page: the account link, the user menu and the day strip carried
an aria-label that left out their visible text. The same class sat in
the coverage meter, the score ring, medication links, instrument cards,
filter pills with a value set, cycle calendar days (named by an ISO
key), admin user and login rows, a few sort and action buttons, and the
French, Spanish, Italian and Polish weekday chips, whose abbreviations
were not part of the day names.

Controls with visible text are now named by it, with any extra purpose
added as screen-reader text; the select pill and calendar days spell
out a name that contains what they show. The day and conversation
strips keep their action as the tooltip.
