refactor(core): use workspace role query instead of isOwner query (#12118)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **Refactor**
  - Updated workspace permission handling to use a unified role field within workspace data instead of separate admin and owner flags.
  - Permission checks now rely on the workspace role for determining admin and owner status.
- **Chores**
  - Removed deprecated queries and types related to admin and owner status.
  - Cleaned up internal logic and variable naming for improved consistency.
