fix: implement EZA_GRID_ROWS grid details view minimum rows threshold

Grid details view had been prevented only by
console width being unavailable.

This changeset implements `EZA_GRID_ROWS`
as secondary grid details inhibitor, preventing
grid details view if the minimum rows threshold
is not reached by grid which would be rendered.

Fixes complaint at eza-community#66 (comment)
