feat: structured screens for SIGN_MODE_TEXTUAL (#13434)
## Description

Refs: #11970

Changes target of `SIGN_MODE_TEXTUAL` rendering to be a structured datatype
instead of lines of ASCII text. This avoids the complexities of in-band, signaling and
allows more capable signing devices not to be hindered by the limitations of those less
capable.
