Fix day/date visibility in dark table headers

text-muted stays dark grey inside table-dark, making dates invisible.
today-col's background !important fought table-dark, turning that cell
light and hiding the white day name. Fix: restore dark bg for today-col
in thead via a scoped rule, use a top-border accent instead, and force
text-muted to a readable white-ish inside dark headers.
