API returns daysOfWeek.flight as a string of ISO weekday digits
("1"=Mon.."7"=Sun) where each character is the number of one
operating day, NOT a 7-char position bitmask. E.g. SU 6188's
flight value is "156" → Mon + Fri + Sat operating; SU 6341's is
"1234567" → daily. The old reader treated it as bitmask and only
checked position[i]==='1', so SU 6188 highlighted only Mon and SU
6341 highlighted only Mon — the highlighting looked random
relative to Angular which uses the digit-list semantics.
Walk the input character-by-character, build a Set<weekdayNumber>,
mark badge active when its day-number is in the set. Defends
against non-digit characters and out-of-range digits. Rewrite the
unit tests to match the real wire format and add a regression
case for the SU 6188 "156" pattern.
