Show rank in the day label for every winner kind, not just sanctoral

Rank display (added in 1fc4bd7) only fired for a plain sanctoral
winner. Every other case -- an active octave day, a named temporal
feast, a season anchor day (Easter, Trinity Sunday, Epiphany), or the
plain ordinal Sunday/feria fallback -- showed no rank at all, which is
what made today's octave day (Aug 18, day 4 of the Assumption's
octave) show no rank. Octave days use the octave's own already-computed
effective rank; anchor days get a fixed Duplex I Class (Ash Wednesday
excepted -- a privileged feria has no duplex-scale rank); the plain
fallback derives a Semiduplex/Feria label from the day's own
temporalCategory, since Sundays/ferias aren't on the duplex scale at
all.
