Subject: [PATCH] feat(web): add workspace contextual sub-nav to sidebar

Detect active workspace via fuzzy matchRoute against /workspaces/$workspaceId
and reveal an animated sub-nav with links to Peers, Sessions, Conclusions,
and Webhooks for that workspace. Sub-nav collapses smoothly when leaving
the workspace context.
