Tweak log attachment implementation after manual testing

[fractalwrench]

Goal

This changeset contains a few tweaks to the log attachment implementation that were required after carrying out manual testing:

• Created screen in example app for log messages with attachments
• Used 'attachments' instead of 'attachment' as endpoint
• Logged a message if an attachment can't be sent due to limits

[priettt]

should we also rename the enum type name? ATTACHMENT -> ATTACHMENTS
