fix(tui): cap detail sidebar height to match monitors panel

SLA daily breakdown no longer overflows past the monitors panel. Detail
sidebar height is capped to monitors panel height via titledPanelH.
SLA daily rows are limited to fit within available space. Logs strip
stays visible in all detail modes.
