refactor(editor): rename doc to store on block components (#12173)

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

## Summary by CodeRabbit

- **Refactor**
  - Unified internal data access by replacing all references from `doc` to `store` across all components, blocks, widgets, and utilities. This affects how readonly state, block operations, and service retrieval are handled throughout the application.
- **Tests**
  - Updated all test utilities and test cases to use `store` instead of `doc` for document-related operations.
- **Chores**
  - Updated context providers and property names to reflect the change from `doc` to `store` for improved consistency and maintainability.

No user-facing features or behaviors have changed.
