Consolidate global routes into study-scoped architecture

Removed global participants, trials, and analytics routes. All entity
management now flows through study-specific routes. Updated navigation,
breadcrumbs, and forms. Added helpful redirect pages for moved routes.
Eliminated duplicate table components and unified navigation patterns.
Fixed dashboard route structure and layout inheritance.
