Feature request: Double-click to select/set default device

[prabhanshu11]

Feature Request

Currently, mouse support in wiremix allows moving focus between items, but there's no way to select or set default a device using mouse clicks.

Current behavior

• Mouse moves focus (works)
• No click action to select/confirm
• Must use keyboard (d key or Enter) to set default or open dropdown

Expected behavior

• Double-click (or single-click) on a device should set it as default (equivalent to pressing d)
• Alternatively, clicking on a focused item could activate the dropdown (equivalent to Enter or c)

Use case

For users who prefer mouse-driven workflows, having to switch to keyboard just to confirm a selection breaks the flow. Many TUI applications (like pulsemixer, ncmpcpp, etc.) support click-to-select.

Suggested implementation

• Double-click on a device → trigger SetDefault action
• Or: Single-click on already-focused item → trigger ActivateDropdown

Would be happy to attempt a PR if you're open to this feature.
