Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@app/Http/Utils/FileUploadInfo.php`:
- Around line 142-167: In the buildFromPayload method, use the normalized
trimmed path variable consistently and always retrieve the actual file size from
storage. Replace the untrimmed $payload['filepath'] with the trimmed $filepath
variable in the $disk->exists() call on line 147, and all subsequent references
including the logging on line 155 and the disk->path() call on line 161.
Additionally, remove the conditional check that allows trusting the
client-provided $payload['size'] value on line 153 and instead always retrieve
the actual size from the disk using $disk->size($filepath), ensuring the
zero-size validation guard cannot be bypassed by forged client metadata.

In `@app/Jobs/FileProcessingJob.php`:
- Around line 36-38: The handle method in FileProcessingJob is not checking the
return value from the postProcessFileFromFileApi call on the injected
IFilePostProcessorService. When the service method returns false, the job
currently completes successfully instead of failing and retrying. Capture the
return value from the postProcessFileFromFileApi call with $this->fileInfoDTO as
the argument, check if it returns false, and throw an exception in that case to
properly fail the job and trigger retries.

In `@app/Services/Model/FileInfoDTO.php`:
- Around line 28-30: The __toString() method in the FileInfoDTO class currently
calls json_encode() directly, but json_encode() can return false on encoding
errors, which triggers a TypeError when returning from a method declared to
return string. Wrap the json_encode call with a null check or ternary operator
to handle the false case, providing a fallback string value (such as an empty
object representation or error message) to ensure the method always returns a
valid string instead of false.

In `@app/Services/Model/Imp/CompanyService.php`:
- Around line 306-308: The finally block in the CompanyService cleanup logic
unconditionally deletes both local and remote files using
cleanLocalAndRemoteFile, which destroys the remote source file even when
processing fails, preventing retries. Modify the logic so that the remote file
(referenced in file_info_dto->filepath) is only deleted on successful processing
completion, while the local file can still be cleaned up in the finally block.
Apply this fix to both occurrences of the finally block that call
cleanLocalAndRemoteFile (around lines 306-308 and 332-334).

In `@tests/oauth2/OAuth2CompaniesApiTest.php`:
- Around line 108-124: The testAddCompanyLogoViaJsonPayload method and other
JSON-flow tests are faking storage disks but still depend on the
file_upload.storage_driver configuration resolving to 'local', making them
vulnerable to environment or config drift. Explicitly pin the storage driver
configuration to 'local' at the beginning of each affected JSON test method
(including testAddCompanyLogoViaJsonPayload and the test at lines 203-219) using
Laravel's Config facade to set the driver value explicitly, ensuring the tests
use the faked 'local' disk regardless of environment settings.
