refactor: Replace aiofile with aiofiles for async file operations

[Cristhianzl]

This pull request updates the local storage service to use the aiofiles library instead of aiofile for asynchronous file operations. The change ensures consistency and compatibility with other parts of the codebase that may use aiofiles.

Dependency update:

• Replaced the import of async_open from aiofile with aiofiles in src/lfx/src/lfx/services/storage/local.py, and updated all asynchronous file open calls to use aiofiles.open instead of async_open. [1] [2] [3]

Walkthrough

This pull request replaces the aiofile.async_open dependency with aiofiles.open throughout the LocalStorageService. The import statement is updated and all file I/O operations are migrated to use the new library, with no changes to control flow or error handling logic.

❌ Failed checks (1 error, 1 warning)

Check name	Status	Explanation	Resolution
Test Coverage For New Implementations	❌ Error	PR refactors aiofile to aiofiles library swap with no new or updated test files included to verify the integration.	Add or update test files to verify aiofiles library integration works correctly and document test results in the PR.
Test Quality And Coverage	⚠️ Warning	The pull request updates core async file-IO operations in LocalStorageService but includes no corresponding tests to validate the new aiofiles behavior.	Add pytest-based async tests for LocalStorageService's write, append, and read methods covering normal and failure cases.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly and accurately describes the main change: replacing the aiofile library with aiofiles for async file operations throughout the LocalStorageService.
Docstring Coverage	✅ Passed	Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%.
Test File Naming And Structure	✅ Passed	The PR modifies only configuration, documentation, and repository files without including any test files, making test naming and structural requirements non-applicable.
Excessive Mock Usage Warning	✅ Passed	Test files demonstrate excellent design with minimal mock usage focused only on dependency injection, real file I/O operations, and actual behavior verification rather than mocked behavior.
