fix(tui): space and F1-F24 keys not handled properly by new keybind system (#3138)

Fixes two keymap issues introduced in #3127:

1. Space key does nothing - Pressing space in the search input didn't
insert a space character
2. F12 not recognized - Function keys (F1-F24) couldn't be used in
`[keymap]` config
