backstage release v3.25.0

(agent-platform) Check before editing or deleting whether agent-manager can open the pull request by @marians — Editing or deleting an agent applied from Git tells you up front when the portal cannot open a pull request for it, and where to change it instead, or asks you to authorize GitHub first when that is all that’s missing.

(agent-platform) Name an agent’s organization beside its name in the Agents list by @marians — In Customize’s Agents list, an agent’s Organization: <name> sits next to its name instead of in a column of its own, so rows of different organizations line up again.
(agent-platform) Give the egress refusal’s real remedy, hide refused egress on coding Harnesses by @marians — A session’s Outgoing connection to <host> blocked says what you can actually do, depending on the agent’s runtime and your rights. On coding Harnesses the agent form shows Network access instead of Extra egress origins, which they refuse.
