fix(codegen): add missing dot when printing import.defer and import.source

[Boshen]

Summary

Fixes the codegen to correctly print import.defer() and import.source() expressions. Previously, the dot was missing, resulting in invalid syntax like importdefer() and importsource().

Changes

• Added missing dot (.) between import and the phase (defer or source) in the ImportExpression code generation
• Added test cases to verify both import.defer() and import.source() are correctly generated

Closes #13971
