feat(textstyle): full Text Style editor — big/TT font, fixed height, flags, annotative

Expands the Text Style manager beyond font/width/oblique: big-font and
TrueType font fields, fixed text height, Backward / Upside-down flags, and
an Annotative toggle (applied live). Bumps acadrust for the annotative
field.
