Promote shell context to the root route

- Wait for the legacy shell bridge/profile before React routes render
- Expose the shell bridge and profile through root TanStack context
- Update issue routes and shell helpers to consume the shared context
- Remove the redundant issues search normalization on read
- Refresh the affected tests around shell bootstrap and routing
