feat(flows): workspace switcher + project-filtered flow list

Mount the shared project switcher (same control as Audit, Approvals
and Runs) in the flow editor's toolbar via the editor's new
toolbarTrailing slot. The list filters by the active project with
'no key = general' display semantics, and new flows are stamped
with the active project's key. Editor pin moved to c4a39a3
(0.25.0 + project separation).
