Fix minimum dependency version support

[egillax]

Summary

• raise dependency floors needed for old-R-compatible installs and add an internal %||% fallback
• make imputation and normalizer SQL generation work with the dependency floor stack
• require DuckDB-backed Andromeda (>= 1.0.0) and remove SQLite-backed Andromeda special cases
• add a manual dependency-floor GitHub Actions workflow

Testing

• Rscript -e 'testthat::test_local("tests/testthat", filter = "andromedahelperfunctions|normalizers|preprocessingData|simulation", reporter = "summary")'\n- R CMD build --no-build-vignettes --no-manual .\n- R CMD check --no-manual --no-build-vignettes --ignore-vignettes --no-tests --no-examples PatientLevelPrediction_*.tar.gz
