fix: bottom-nav related mobile cutoffs (#805, #806, #807)

TransportModal + ReservationModal: move Save/Cancel into the Modal's
footer slot so they stay visible on long forms (same fix as
PlaceFormModal in this PR).

DayDetailPanel: the floating day info panel was anchored at a fixed
bottom: 96px which didn't account for safe-area-inset-bottom, causing
it to overlap the bottom nav on devices with a home indicator. Use
calc(var(--bottom-nav-h) + 20px) so it always floats above the tab
bar with a safe gap.
