Merge feature/workbench-w4-resources into unify/skills-20261112

Conflicts combined W1 (Inbox leaves the Stream for Tasks, Waits on Operator) with W4 (Resources tab): five tabs with Resources, Stream keeps only the Firewall, the inbox hash keeps its redirect; index.html.j2 includes both diffs.js and resources.js.
