Shunsuke Hayashi f90aabf9a8 fix(python): resolve module-qualified calls via moduleAliasMap
Previously, Python was added to WILDCARD_IMPORT_LANGUAGES which expanded
all exported symbols into namedImportMap using first-seen wins. This caused
`auth.User()` to incorrectly resolve to `models.py:User` when both modules
exported a class named User.

Root cause: Python `import models` is a namespace import, not wildcard
symbol expansion. Expanding all symbols produces ambiguous bindings that
cannot be disambiguated later.

Fix:
- Remove Python from WILDCARD_IMPORT_LANGUAGES
- Add ModuleAliasMap (callerFile → alias → sourceFile) to ResolutionContext
- In synthesizeWildcardImportBindings, build moduleAliasMap for Python
  using the filename stem as the module alias
- In resolveCallTarget, add module-alias disambiguation step: when multiple
  candidates survive filtering and the receiver name matches a module alias,
  narrow candidates to the aliased file

Result: `models.User()` → models.py:User, `auth.User()` → auth.py:User
even when both modules export a class named User.

Adds regression test for the ambiguity case.
