Account for wrapped chrome lines in height budget

layout-line-count assumes the non-session UI always uses exactly 5/7 lines, but footer-line (and occasionally header-line) can exceed the terminal width and wrap to extra rows. On narrow terminals (for example compact view around 40 columns), this overestimates available-lines, so visible-session-blocks still emits too many session lines and the final screen output overflows, which can scroll the selected item out of view despite the new overflow logic. The height budget should be computed from wrap-aware rendered line counts rather than fixed constants.
