Core: Float context menu button on top of story titles in sidebar

[ghengeveld]

Closes #29651

What I did

Renders story context menu buttons and status icons on top of the story/component/folder title to prevent the sidebar from reflowing on hover. Transparent backgrounds have been replaced with opaque colors to prevent the text from showing through. Buttons have a slight outer glow to make it look like a gradient.

Greptile Summary

Based on the provided information, I'll create a concise summary of the PR changes focused on improving the sidebar's context menu and status icon rendering:

Improves sidebar rendering by making context menu buttons and status icons float on top of story titles using absolute positioning, preventing layout reflow issues when hovering.

• Modified Tree.tsx to use absolute positioning for menu buttons and handle overflow properly
• Updated StatusButton.tsx to include opaque backgrounds and box shadows instead of transparent backgrounds
• Added theme-specific color calculations for better visibility and contrast
• Implemented media queries to handle desktop/mobile breakpoint differences
• Fixed issue [Bug]: Showing/hiding the context menu can cause the whole sidebar to reflow #29651 where showing/hiding context menus caused sidebar reflow

No significant changes detected, all good. 👏

[ghengeveld]

As discussed with MA, I've updated the status icons to never overlay the text but instead claim space for themselves. Only the context menu button should overlay the text because it's visible only on hover.
