The rendered MText preview is now interactive: drag across glyphs to select
a character range and apply toolbar formatting (bold, italic, underline,
overline, strike, case, alignment) to exactly those characters.
The text layout gains an opt-in pass that emits one world-space box per
visible character carrying its reading-order index; the editor maps those
boxes into the preview frame, hit-tests pointer drags against them, and
highlights the selection. Formatting splices the matching inline codes into
the raw value at the selected byte range (mapped via a code-aware visible-
character scanner). With no preview selection the Edit-box path is unchanged.

The editor opens in preview by default and switches body views with a
segmented Edit | Preview control placed between the toolbar and the body
(active tab highlighted). All toolbar properties feed the rendered preview.

MTEXT (and double-clicking an MText) now opens an in-place editor anchored
at the insertion point instead of typing a single line on the command line.
The editor has a two-row formatting toolbar: text style / font / height,
bold, italic, underline, overline, strike, upper/lowercase and a colour
dropdown on top; oblique angle, width factor, character spacing, paragraph
alignment, justification, line spacing and OK/Cancel below. Character
toggles wrap the selection in DXF inline codes; global fields apply as
leading runs or entity properties.
Editing is shown in the editor's own area, not on the drawing: a Code/Preview
toggle switches between the raw text input and a rendered preview canvas that
draws the tessellated glyph strokes at real size, scrolling when the text
outgrows the view. The MText box keeps a fixed width so text wraps to the
next line instead of stretching into one line.

- Added SVG icons for text formatting options (bold, italic, underline, overline, strike, uppercase, lowercase).
- Introduced a new `MTextEditorState` struct to manage the state of the MText editor.
- Implemented functionality to open the MText editor from the command line and edit existing MText entities.
- Added message handling for various MText editor actions (formatting, height, style, font, justification, alignment, line spacing).
- Created a dedicated preview area for MText rendering within the editor.
- Updated the command structure to support opening the MText editor and handling text input.
- Refactored existing MText command logic to integrate with the new editor.
