:bug: Set filenames for task details downloads

[sjd78]

Resolves: #2030

On the Analysis details / Task details page, the log viewer allows downloading of the file being displayed. Set a filename that matches the attachment name when doing the download.

File names used:

• Base log view -> "log-${taskId}"
• Merged log view -> "log-merged-${taskId}"
• Task attachment -> attachment name

Due to the way the CodeEditor PF5 component implements the download action, only file extensions of known file types can be used. Any log or attachment files will have file extensions of .yaml or .json or .txt depending on the detected file type. File type detection is only using attachment name file extensions currently, and only differentiates between yaml and json with a default to plain text. For example, given an attachment name, the download file name will be:

• git.output -> git.output.txt
• addon.log -> addon.log.txt
• settings.yaml -> settings.yaml
• data.json -> data.json
