Let the editor fill the window, with a configurable measure

[x3m]

The editor measure is hardcoded at 65 average character widths. That is a classic default for prose, but on a large display most of the window is empty margin, and notes with long list items (meeting minutes, task lists) wrap early. It also caps information density: combined with text-size shortcuts (#25), shrinking the font just shrinks the column — you never fit more text per line.

This lets the text use the window instead:

• By default the editor fills the available width, keeping the existing ten characters of margin on either side (the width - 20ch term that already existed).
• The classic fixed measure stays available via the existing QSettings store: [layout] editorColumns in omawrite.conf — 0 (default) fills the window; a positive value gives a fixed measure (clamped ≥20, still capped by window width); 65 restores today's look exactly. No new UI.

To be upfront: this changes the default look — the column is wider on large windows. If you'd rather keep 65 as the default, the same patch works with the default flipped; happy to adjust.

Tested on Omarchy (Qt 6.11) in both modes, including the interplay with #25 (smaller font → more characters per line when filling the window).

Greptile Summary

This PR makes the editor fill the available window width by default while preserving a configurable fixed-column measure.

• Adds a persistent [layout] editorColumns setting with bounded fixed-width behavior.
• Raises the documented and packaged minimum Qt version to 6.5 for the QtCore Settings QML type.
• Updates the editor-width calculation while preserving margins and the classic 65-column option.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
