This PR fixes an issue where `realizeConst` would generate auxiliary declarations (like `_sparseCasesOn`) using the original defining module's private name prefix rather than the realizing module's prefix. When two modules independently realized the same imported constant, they produced identically-named auxiliary declarations, causing "environment already contains" errors on diamond import. The fix re-privatizes the constant name under the current module before passing it to `withDeclNameForAuxNaming`, ensuring each realizing module generates distinctly named auxiliary declarations.
