fix(inspector): scope copy-button reset timeouts per button

The previous copyResetTimeout field was a single instance-level number,
shared across every code block in a multi-block announcement. Clicking
Copy on block A then block B cancelled block A's reset timer, leaving
block A stuck on "Copied" forever.

Switch to a WeakMap<HTMLButtonElement, number> so each button manages
its own pending reset and is naturally cleaned up when the announcement
re-renders. Also keep aria-label in sync with the visible text label so
screen-reader users hear "Code copied" while sighted users see "Copied".
