Fix: layout-transition false positives on JSX quoted transition values (#548)

The value-capture regex stopped only at ;{}, so in single-line JSX
style objects it ran past the closing quote and swallowed later
properties, flagging layout props that were never transitioned. The
capture now stops at the matching closing quote when the value is a
quoted string, falling back to the old bounds for real CSS.
