fix: use fallback args when tool-specific keys are missing in labels

When toolArguments doesn't contain the expected key (e.g. 'path' for
view), fall back to the first usable string value from any argument
key instead of showing misleading placeholders like 'Viewed a file'.
When no arguments exist at all, show just the tool name.
