Add Iris copy IP buttons, to make it easier to SSH into stuff.

@claude there's got to be a shared components area we can put things like these copy commands?

Extracted copy button into shared component

• Read PR changes to understand the copy button pattern
• Explore the dashboard component structure for shared components
• Create CopyButton.vue in components/shared/
• Refactor EndpointsTab.vue, FleetTab.vue, WorkerDetail.vue to use it
• Run pre-commit and push

Yes — there's already a lib/iris/dashboard/src/components/shared/ directory with reusable components (DataTable, InfoCard, StatusBadge, etc.).

I extracted the duplicated copy-to-clipboard button into a new CopyButton.vue shared component, reducing ~82 lines of duplicated logic/SVG across 3 files down to a single 30-line component + ~44 lines of clean usage.

The component takes a value prop (the address to copy) and an optional title prop. Each instance manages its own copied/checkmark state internally — no need for parent ref tracking.

Testing: Pre-commit checks pass. This is a pure Vue template refactor with no behavior change — the copy logic (strip protocol/port, write to clipboard, show checkmark for 1.5s) is preserved exactly.
