tasks: compare due dates in the caller's day, not in UTC

dayDelta truncated both instants to a UTC day. A task due at 02:00 Moscow time tonight read as due tomorrow, and one due at 23:00 last night read as due today, so the two classes that decide the whole order were assigned from the wrong calendar. Both sides are now truncated in now's location. Dated work also lost to age alone because the later-due score sat below the age cap, and the tail said "и ещё 3" with no noun and no Russian plural agreement. The page hardcoded time.Now, so none of this was testable from a fixed clock. It now takes an injectable clock, parses the due date in that clock's location, parses ids and weights with strconv instead of a hand-rolled scan, caps the resolved table and says so, shows who resolved each row, and reports a promotion as the confirmation it is. Found in review of #61.
