feat: add fill toggle and opacity slider for bulk annotations

[igoroctaviano]

Summary

• Add UI controls in the annotation group display settings for enabling fill on polygon annotations
• Toggle switch to enable/disable fill
• Opacity slider (0-1) that is disabled when fill is off
• Fill settings only shown for POLYGON, RECTANGLE, and ELLIPSE graphic types

Changes

• AnnotationGroupItem.tsx: Added fill toggle, fill opacity slider, and handlers
• AnnotationGroupList.tsx: Updated interface to include fill style options
• SlideViewer.tsx: Updated style change handler to pass fill options to DMV

Dependencies

• Requires dicom-microscopy-viewer PR: feat: add fill support for bulk annotation polygons dicom-microscopy-viewer#279

Test plan

• Load a slide with bulk polygon annotations
• Open display settings for an annotation group with POLYGON graphic type
• Verify the Fill section appears with toggle and opacity controls
• Enable fill and verify polygons render with fill color
• Adjust fill opacity and verify the opacity changes
• Verify the fill opacity slider/input is disabled when fill is off
• Verify POINT and POLYLINE annotation groups do not show fill settings
