made the titlebar have the host label and hide tab bar when only one tab

added a lot of logic fore foreground color calculation, based on luminance of foreground, background and selectedAnsi colors
fixed fallback when opening the first session
fixed text of unselected tabs being unreadable
added tint var to hostsmanager to get accentcolor
reduced ios version to ios 16
