Detail page: expand view controls (Changes only + All/Filtered)

[elkraneo]

Context

We already added an aligned/timeline view on detail pages.

Idea

Add caniuse-style controls to make timeline more useful:

• Changes only mode to hide unchanged platform rows.
• All vs Filtered toggle so users can quickly switch between full context and focused deltas.

Scope

• UI controls in detail view.
• Filtering logic for timeline rows.
• Maintain current behavior as default (All).

Acceptance Criteria

• User can toggle Changes only on/off.
• User can toggle All and Filtered states.
• No regression in mobile layout and current timeline rendering.
