Per on-device review, render the week number as a full-height tonal pill
mirroring the day cells' geometry (secondaryContainer tint, same rounded
shape and gap), with the number centred — so the gutter reads as part of the
grid rather than a floating chip. This diverges from the Week view's small
header chip, so revert the shared-badge extraction: restore WeekScreen's
private badge and drop ui/common/WeekNumberBadge.

Extract the Week view's calendar-week badge into a shared ui/common
component and reuse it for the Month grid's week-number gutter, so the two
views show week numbers in the exact same format. The gutter now centres the
badge vertically in each row (was pinned to the day-number band) and is
widened to seat the badge.

Add an opt-in left gutter to the Month grid showing the ISO calendar-week
number, gated by a new "Week numbers" display setting (default off). The
number is computed on each row's first day — the same basis as the Week
view's badge — so the two views agree, and rendered as a low-emphasis
onSurfaceVariant label so it recedes across all six rows rather than
competing with the event bars. The weekday header reserves a matching
gutter so the day columns stay aligned.
