refactor(renderer): dismantle useAppController 47-prop god-hook

Sections now subscribe directly to the Zustand store via useSectionContext
(shared data derivation) and useAppStore fine-grained selectors. Delete
useAppController, useExecutionController, useOrganizationController, and
useCommunicationController; the three domain forwarders held no logic
beyond re-exporting store slices.

SectionContentView becomes a 50-line layout dispatcher taking only
{section, error, pageTransition}; cross-domain run actions (startRun /
cancelRun) move into App.tsx and are exposed to sections through a new
AppActionsContext alongside refresh / setError / openPathWithFeedback.
App.tsx now calls useUIController + useCompanyController directly and
composes palette + navigation plumbing itself.
