Fix quoted identifiers in enum DEFAULT values causing CE1613

Strip surrounding quotes from each segment of dotted qualified names
in DEFAULT value expressions. Previously, `expr.GetText()` preserved
raw quotes (e.g. MaisonElegance."FormSubmissionStatus".StatusNew),
producing invalid enum references that MxBuild could not resolve.

Fixes #11
