Format misc/api.func: spacing and heredocs

Clean up formatting in misc/api.func for readability. Normalized spacing in the categorize_error case patterns, removed trailing blank-space lines, and standardized detect_gpu blank-line spacing. Converted heredoc assignments to use multiline $() style for JSON_PAYLOAD in post_tool_to_api, post_addon_to_api, and post_update_to_api_extended, and added a final newline at end of file. No functional changes intended; purely whitespace/formatting cleanup.
