feat(teams): show the full task UUID in the task detail dialog with one-click copy (#1560)

The short identifier (T-015-cc8e) carries only the last four hex chars
of the UUID, while every agent-facing surface — the team_tasks tool
(get / retry / cancel / comment) and the teams.tasks.* RPCs — takes the
full UUID. A human looking at the dashboard therefore had no way to name
a task to the lead in chat. Show the UUID next to the identifier and
status badges, copy it to the clipboard on click, with a short "copied"
confirmation.
