Bug ID: 527354
Summary: The editor context menus appear **transparent** (with
no solid background) when using a color scheme that
has alpha channels (translucent schemes). The menu
blends into the note text, making items hard to read
and to locate.

Adds a solid background to the editor context menus, which currently appear
transparent on color schemes with alpha.
# Bug Report
**Product:** Marknote
**Component:** Editor (context menus: `TextFieldContextMenu` and
`BlockContextMenu`)
**Version:** 1.6.0 and current master
**Type:** Visual bug / readability
## Summary
The editor context menus appear **transparent** (with no solid background) when
using a color scheme that has alpha channels (translucent schemes). The menu
blends into the note text, making items hard to read and to locate.
## Steps to reproduce
1. Use a color scheme whose background carries alpha (e.g. `BackgroundNormal`
with alpha < 255).
1. Open a note with text in Marknote.
1. Right-click on the text **while editing** (the Cut/Copy/Paste menu) — or on
a block while not editing.
1. Observe that the context menu is see-through, with no background, blending
into the content.
## Observed behavior
The menu declares no `background`. The control style (`org.kde.darkly`,
`Menu.qml:98`) fills the background with `Kirigami.Theme.backgroundColor`,
which **preserves the alpha channel of the color scheme**. On translucent
schemes the result is an almost invisible menu on top of the text.
## Expected behavior
The context menu should have an **opaque** background that stays readable over
any content, following the theme colors (RGB), with a border and rounded
corners.
## Fix
Explicitly declare a `background` on both menus, using the theme RGB but
**forcing the alpha to 1.0**, so the menu stays legible even on translucent
schemes:
```qml
background: Rectangle {
color: Qt.rgba(Kirigami.Theme.backgroundColor.r,
Kirigami.Theme.backgroundColor.g,
Kirigami.Theme.backgroundColor.b,
1.0)
border.color: Kirigami.Theme.separatorColor
border.width: 1
radius: Kirigami.Units.smallSpacing
}
```
Files: `src/qml/TextFieldContextMenu.qml` and `src/qml/BlockContextMenu.qml`
(the latter also needs `import org.kde.kirigami as Kirigami`).
## Note
On opaque schemes the defect does not show, since the default alpha is already
255. It becomes obvious on translucent schemes — an increasingly common setup
in Plasma.
