Manage a deployment without opening it

What it does
Every row on the Deployments page gained a ⋮ menu — Rename, Edit, Share, Copy Link, Delete — and the same actions arrived on the Connections table inside an agent, next to a new Open button.
Why it matters
Renaming four direct links, or pulling the share snippet out of one embed, used to mean opening each deployment in turn and coming back.
How it works
The menu adapts to the deployment: Share opens the embed share modal and only appears on embeds, Copy Link puts the public URL on your clipboard and only appears on direct links. Rename and Delete are hidden for workspace viewers.
The Connections table on an agent — the list of that agent's own deployments and portals — already had Rename, Edit, and Delete. It now has Share and Copy Link too, plus an Open button on the rows with a public URL.
