fix: Better handling of Escape and Enter keys

[marc2332]

Fixes

• No more need to press twice the Enter key in ConfirmQuit, Welcome or Assistant routes.
• Writing (and therefore pasting) was allowed while rendering the Assistant route. You could run stuff by pasting scripts with breaklines without the need to go to the terminal route

LMK if I broke something but from my own tests all went just fine

[marc2332]

for context: The double enter issue was caused because the first press of Enter was not requesting a rerender, this was because has_key_wait was returning true in all cases except when the route was already Terminal, causing the first render not happen.

The second render was triggered simply because the route in that moment was the Terminal, and therefore an Enter in the shell causes a break of line, leading to a rerender.
