[WIP]: Fixing filter button in marker hover panel

[KaranPradhan266]

Closes: #5704

Tooltip Filter Button Default Behavior

Changes

• The tooltip filter button now defaults to visible by setting showFilterButton = true in
  src/components/tooltip/Marker.tsx.
• Timeline tooltips explicitly opt out of the filter button by passing
  showFilterButton={false} in:
  • src/components/timeline/Markers.tsx
  • src/components/timeline/TrackNetwork.tsx
  • src/components/timeline/TrackCustomMarkerGraph.tsx
• Marker charts continue to display the filter button via the existing prop in
  src/components/marker-chart/Canvas.tsx.

Tests

• Updated Jest snapshots to reflect the new tooltip behavior and minor download-size text changes:
  • src/test/components/__snapshots__/TrackCustomMarker.test.tsx.snap
  • src/test/components/__snapshots__/TrackNetwork.test.tsx.snap
  • src/test/components/__snapshots__/MenuButtons.test.tsx.snap
