Keep New Workspace on the current project (#1806)

* fix(app): keep New Workspace on the active project

New Workspace preselection was falling back to stale remembered host state when multiple hosts existed. Pass durable active-project context from workspace entry points and centralize initial host selection so stale offline hosts cannot steal the form while startup restore remains last-workspace only.

* fix(app): address New Workspace review feedback

* fix(app): stabilize New Workspace host selection

* fix(app): preserve New Workspace host fallback

* test(app): loosen stale-host project assertion

* fix(app): prefer reachable new workspace hosts

* fix(app): avoid stale offline workspace preselect

* fix(app): prefer online project hosts
