test(apps): cover no-env dry-run defaults + numericAsFloat string path

Address CodeRabbit review threads on PR #1735:
- numericAsFloat: add numeric-string cases ("13.5", " 13.5 ", int, empty)
- db-data-import: assert dry-run omits env when --environment unset (table
  still defaults to file basename)
- db-quota-get: assert dry-run omits env when --environment unset
