fix: locale-dependent category duplication bug (#956)

* fix: locale-dependent category duplication bug

* fix: use family locale for investment contributions category to prevent duplicates and handle legacy data

* Remove v* tag trigger from flutter-build to fix double-runs

publish.yml already calls flutter-build via workflow_call on v* tags,
so the direct push trigger was causing duplicate workflow runs.
