Refactor: Replace pluck(:id) with ids method

Use the more idiomatic ActiveRecord ids method instead of pluck(:id)
across controllers and models. The ids method is more readable and
explicitly conveys the intent to retrieve primary key values.

Changes:
- BoardsController#edit: Use @board.users.ids
- Board::Storage: Use cards.ids, Comment.where().ids, and ActionText::RichText.where().ids
- User::Accessor: Use account.boards.all_access.ids

This change improves code clarity while maintaining the same functionality.
