  Ryuta Kamizono

• The db:prepare task no longer loads seeds when a non-primary database is created.

  Previously, the db:prepare task would load seeds whenever a new database
  is created, leading to potential loss of data if a database is added to an
  existing environment.

  Introduces a new database config property seeds to control whether seeds
  are loaded during db:prepare which defaults to true for primary database
  configs and false otherwise.

  Fixes #53348.
