The Avalonia port had placed the UI app in an ILSpy.* namespace tree,
while the csproj RootNamespace and every prior release (through 10.1)
use ICSharpCode.ILSpy.*. Restoring the historical namespace reduces the
public API diff against release/10.1 for plugin authors and removes the
shadowing that forced global:: qualifiers in the test project. The
Images class and AccessOverlayIcon enum move back into the root
namespace (as in 10.1), since an ICSharpCode.ILSpy.Images namespace
would shadow the Images class for all code inside ICSharpCode.ILSpy.

Clicking inside the open flags filter popup could act on the
DataGridColumnHeader underneath: unhandled press/release pairs bubbled
out of the popup into the header (which treats them as a sort click
and flashes its pressed visual), and on X11 overlay popups the
light-dismiss machinery could even re-target a click's press directly
at the header while the popup stayed open.
The filter UI is now hosted in a Flyout attached to the funnel icon
instead of a hand-rolled Popup parked in the header's panel. Avalonia
positions Popup as the low-level primitive and recommends Flyout for
attached pickers: light dismiss, Escape-to-close, focus handling, and
theme-correct presenter chrome come built in (the old hard-coded white
background was also wrong in dark mode). The flyout content swallows
unhandled wheel and press/release events, since its internal popup is
still logically parented to the funnel inside the header.
A headless end-to-end regression test drives a real DataGrid with
overlay popup hosts (the X11 OverlayPopups=true configuration the app
runs with) and raw input through the funnel and every visible flyout
control, asserting the header never sorts and never receives an
unhandled press or release.

Label and input now share the same Panel slot inside a horizontal DockPanel —
the funnel icon docks right and exactly one of {label, input} is visible at a
time. Hovering the header (or setting a filter, or opening the popup) swaps
the column name out for the input; otherwise the label stays. Two-row stack
is gone, so the data-rows no longer shift down when an input gets revealed.

Three unit tests pin down the bridge between the column-header TextBox
that MetadataColumnBuilder bakes into each header and the page model:
typing into the box updates ColumnFilter.Text, programmatic filter
changes push back to the box, and either direction raises the
page-level ColumnFilterChanged event the view subscribes to.
