refactor: move shared hooks from ui/hooks to shared/hooks (#729)

Reorganize hook structure to follow vertical slice architecture:
- Move useSmartPolling, useThemeAware, useToast to features/shared/hooks
- Update 38+ import statements across codebase
- Update test file mocks to reference new locations
- Remove old ui/hooks directory

This change aligns shared utilities with the architectural pattern
where truly shared code resides in the shared directory.
