👉 Touch optimizations for context menus

[tcatlas]

📋 Description

Adds the ability to open the context menu via:

1. Single tap - Server list
   • Reasoning was a single tap on the server list does not currently have a purpose, and a long press is used for reordering.
2. Single tap - Active session tab
   • Same as 1, except a single tap on an inactive tab is used to switch to the tab. I figured it is much more rare that a user would want to access the context menu of an inactive tab.
3. Long-press - Terminal view area
   • A single tap is generally used for grabbing input, and I figured a single tap for context menu would be annoying.
