FX.122 CadCraft: MTEXT OK button and part-text height, Text style in Annotate, command drop-down list, Multiline tool

Lab pass 37 feedback (Mohammad Imtaar, 2026-11-07) listed what still failed. Fixed in a Discord member: (1) the MTEXT box had no OK or Cancel button (they were made but never added to the box); (2) a new size typed for a selected part of the text was lost because the size box took the focus and the selection with it, so the whole text changed or nothing did; the selection is now kept the moment the box takes focus, and Enter leaves the box once; (3) the Text style tool was missing from the Draw toolbar's buttons, so the ribbon's Annotate tab had nothing to press, and the Ribbon style's Annotate tab had no text group; both added (Text, Paragraph, Text style); (4) typing in the command line now shows a drop-down list of every command that starts with the letters (arrows + Enter, or a click); (5) MLINE did not exist: new multiline (parallel polylines, Scale, Lines 2-8, Justification, Close, Undo) with a Multiline button in Draw.
