Pull Request Overview

This PR fixes S3 file path handling issues in two areas: correcting the ParseDirPath parameter for downloading files and fixing the S3 path construction for event log downloads.

• Changed DownloadFileToDir to use isFile=true parameter when parsing file paths
• Refactored S3 path construction in downloadWithRetry to correctly build the path from event ID instead of incorrectly concatenating with local path

File	Description

api/eventlog/db/eventFilePlugin.go	Fixed S3 path construction by building it directly from event ID instead of using incorrect path concatenation

The comment on line 208 is now misleading. The localPath parameter is no longer used in the path construction logic, so describing its expected format is confusing. Consider updating the comment to reflect that the S3 path is constructed directly from the eventID parameter instead.
