Match Angular mini-list header/time sizing + soften accordion headers

Measured computed styles on the deployed Angular reference:
  mini-list flight-number: 16px / 400 / #000  (mine: 12px / grey)
  mini-list time:          20px / 500 / #022040 (mine: 17px / 600 / #222)
  'Детали рейса' header:   16px / 400 / #333  (mine: 18px / 500 / #222)
  'Расписание рейса' hdr:  16px / 400 / #333  (mine: 18px / 500 / #222)

React's mini-list was reading the carrier+number as secondary metadata
and the time as a loud bold chunk; Angular reverses the hierarchy —
the carrier+number is the tile's identifier, the time is a darker navy
number-group. Retune both. Also drop the collapse-header weight on
both details+schedule accordions so they read as section separators
rather than section titles; the row content below is the focus.
