Swaps all four DateTime.UtcNow.Date same-day checks in PackController for
_calendar.ResetReady() — daily-single open, /pack/info daily-single gate,
FreePacks /pack/info visibility, FreePacks /pack/open quota. Removes the
TODO(daily-reset) comments; ToDto promoted from static to instance so it
can see _calendar.
Also fills in GameCalendarConfig.ShippedDefaults() (required by the
[ConfigSection] discovery in SVSimDbContext.EnsureSeedDataAsync — bootstrap
throws without it).
