Keep composer autocomplete visible after route hops (#1851)

* fix(app): keep composer autocomplete visible after route hops

Workspace callers now express only the target workspace. The navigation helper chooses whether to pop to a mounted host route or fall back, and active-workspace tracking ignores stale hidden route params while app-wide routes are foregrounded.

* test(app): address workspace navigation review

* fix(app): parse decoded legacy workspace routes

* fix(app): ignore decoded legacy tab routes

* test(app): use canonical offline workspace route
