Tab (or Down/Enter on a field) now cycles through the three text fields
and then onto [ Continue ] and [ Cancel ] buttons at the bottom of the
form. Enter or Space activates the focused button. Ctrl-G still
confirms immediately from any position. Escape still cancels.
The form window is trimmed from h=16 to h=13 since the buttons replace
the now-redundant empty space below the password field.

Ctrl-S (0x13) is the XOFF flow-control character; terminals intercept it
before curses sees it, causing output suspension in Konsole and others.
Replaced with Ctrl-G (0x07 / BEL) which has no terminal-level meaning.
Updated hint bar and test stub accordingly.
