fix: set solid palette on textBrowser context menu (#1574)

* fix: set solid palette on textBrowser context menu

The standard context menu created by QTextBrowser::createStandardContextMenu()
inherits no explicit background, causing compositing window managers to render
it transparently over the password content. Explicitly root the menu's palette
in QApplication::palette() to guarantee a solid background — same principle as
the textBrowser stylesheet fix in #967.

* fix: scope field stylesheets so context menus render opaque

The template-field value widgets (QTextBrowser / password QLineEdit) and
their buttons carried unscoped stylesheets ('background: transparent;').
Qt cascades unscoped widget stylesheets into child popups, so the fields'
standard context menus inherited the transparent background and rendered
see-through.

Scope every rule to its widget type (QPushButton / QLineEdit, QTextBrowser)
so the transparent background applies only to the field and not to the child
QMenu, which then falls back to the opaque native menu background.

Also reparent the main textBrowser's standard context menu to the main
window (away from textBrowser's stylesheet) for the same reason.
