fix dialog navigation and sidebar data construction

Dialog: use consistent cl-tty.dialog: prefix for all select accessors.
The :cl-tty.select and :cl-tty.dialog packages each define their own
SELECT class with separate accessor generic functions. Mixing prefixes
caused "no applicable method" errors. Now all 14 references use
cl-tty.dialog: (make-select, select-filter, select-next, etc.)

Sidebar: fix sidebar-lines append arguments. Each item must be a
proper list of cons cells, not a bare cons. Replaced all quoted
'("x" . :y) with (list (cons "x" :y)). Also fixed the quoted
cons call that was never evaluated.

Bash script: add --disable-debugger and --eval '(uiop:quit 0)' to
the tui sbcl invocation. Prevents the debugger from entering raw
terminal mode on error and ensures clean exit.

cl-tty: delete stale select-package.lisp and select.lisp orphan files
(not tangled by any current org file).
