The day picker used a Popover-based JalaliDatePicker that only showed two
empty text inputs on the booking page — the calendar was hidden until you
clicked the input, so it never matched the design. Replace it with an
always-visible inline two-month calendar (InlineJalaliMonth) rendered side
by side: current month on the right, next on the left (RTL), weekday
headers, Fridays in red, disabled days greyed, selected day in orange,
shared month navigation on the outer edges. Preserves the existing
contract: setDate(unix timestamp), disabledDates[], auto-select nearest
available day.
