DataView: forward align on Filters/DisplayControls, and let Search control its leading icon

Summary

Two DataView controls hard-code a positioning / rendering detail and expose no prop to change it, even though the underlying primitive already supports it.

1. DataView.Filters and DataView.DisplayControls — popup alignment is fixed.
2. DataView.Search — the leading magnifier icon can't be removed or replaced.

1. Forward align on Filters and DisplayControls

• DataView.DisplayControls exposes trigger + hideViewSwitcher/hideOrdering/hideGrouping/hideDisplayProperties, but no align.
• DataView.Filters exposes trigger + classNames, but no align.

The underlying Menu.Content / Popover.Content already extend Base UI's Positioner.Props and accept align / side / sideOffset; these controls just don't forward them.

Request: expose align (and ideally side / sideOffset) on both DataView.Filters and DataView.DisplayControls, forwarding to the underlying menu / popover. Default to today's behavior. Base UI's Positioner already handles collision flip/shift, so this is prop-forwarding only.

2. Let Search control its leading icon

DataView.Search extends the base Search, whose props are Omit<InputProps, 'leadingIcon'>. The base Input accepts leadingIcon, but Search removes it and hard-codes a magnifier, with no supported way to hide or replace it.

Request: re-expose leadingIcon on Search (settable to a custom node or null), or add a showSearchIcon={false} / hideIcon flag. Default keeps the magnifier.

Willing to contribute

Happy to open a PR if the approach looks right.

Locate the DataView.Filters, DataView.DisplayControls, and DataView.Search implementations, then inspect the underlying Menu.Content, Popover.Content, and base Search/Input prop definitions. Forward the requested positioning and leading-icon props while preserving current defaults, and verify the component behavior with the existing test setup.
