feat(bar): enhancing the media widget

The Media widget has been enhanced with a new MediaDisplayFormat
configuration option that controls how the widget is displayed. It
supports seven formats: Icon, Text, IconAndText (the default),
ControlsOnly, IconAndControls, TextAndControls, and Full.

The widget now detects whether the Previous and Next buttons are
actually available for the current media session using the Windows Media
Control API. When a button is not available, it appears dimmed at 50
percent opacity and clicking it has no effect.

Tooltips were added to improve usability. Hovering over the media info
label shows the full artist and title text, which is helpful when the
text is truncated. The Play/Pause button also shows the media info on
hover.

The rendering logic was refactored to properly handle right-aligned
widgets.

When the Media widget is placed in right_widgets, the UI renders items
from right to left, so the code now renders elements in reverse order to
ensure the visual appearance remains consistent regardless of which
panel the widget is placed in.
