fix(settings): adjust log path copy

[samuv]

• Fixes a bug where getMainLogContent() (the full log file content) was being fetched and stored in logPath state. The old useEffect called getMainLogContent() and set the result as logPath, so when a user clicked "copy", they'd copy the entire log file content instead of the file path. The displayed text showed the correct path (LOG_PATHS[platform]), but the clipboard got the wrong value.
• Reuses CodeBlockWithCopy instead of the inline copy button implementation, which also brings better UX (timeout ref cleanup, consistent styling).

Pull request overview

This PR fixes a bug where clicking the copy button in Settings → Logs copied the entire log file contents instead of the file path. The root cause was that the code called getMainLogContent() (which returns log contents) and stored the result in logPath state, while displaying the correct path from LOG_PATHS constant.

Changes:

• Removes incorrect async state management that fetched log contents into logPath
• Simplifies to directly use LOG_PATHS constant based on platform
• Refactors to use existing CodeBlockWithCopy component instead of custom copy implementation
