Keep selected projects when switching hosts (#2700)

* fix(app): preserve project selection across hosts

Rendered project identity and persisted equivalence were conflated after duplicate-project handling. Keep them separate so host changes resolve selectable equivalents deterministically without resetting legacy sidebar identity.

* fix(app): restore selected clone after host round trip

Keep manual origin and current destination placements separately so switching back restores the chosen checkout while archive gaps preserve the active host selection.

* fix(app): key status icons by project view

* fix(app): preserve origin during archive gaps
