terminal: avoid high cpu usage when not focused
When running dynamic tui applications (such as btop, htop, etc.) in the
embedded :terminal and focusing an account tab, every tui application
change triggers a full redraw of the whole window. When the message list
is focused, this leads to high cpu usage because of the computationally
intensive templates parsing and ansi sequence handling.
Only redraw when the terminal is focused. Do not use tcell Watch and
Unwatch functions since these completely disable all widget updates,
including title changes and terminal close events.
