feat(medications,coach): the take-now prompt joins the schedule grammar and the coach opens in place

An open take-window renders as the right-aligned value of the next-
intake row — same label/value columns as every other card line —
instead of a standalone line above the slot; the escalation tiers
(late, very late, taken-early) keep the top line. The coach launcher
opens the side drawer on the page you are on instead of navigating to
the chat page, and grows to the standard FAB size.
