/// The abstract base class for all account-related states used by the AccountBloc.
///
/// Extends Equatable to enable value-based comparisons between state
/// instances. Subclasses should provide the relevant properties by
/// overriding `props` so that the bloc can correctly determine whether
/// the state has changed.
 
/// Represents the initial state of the account feature.
///
/// Used before any account-related action has started or when the bloc
/// has been freshly created.
 
/// Indicates that an account-related operation is currently in progress.
///
/// This state is typically emitted while fetching account data, creating,
/// updating, or deleting an account so the UI can show a loading indicator.
 
/// Emitted when a collection of accounts has been successfully loaded.
///
/// Contains:
/// - `accounts`: the list of Account models retrieved from the repository.
///
/// Use this state to display fetched account data in the UI.
 
/// Represents a successful account operation that does not necessarily
/// carry account data (e.g., after creating, updating, or deleting an account).
///
/// Contains:
/// - `message`: a human-readable success message that can be shown to the user.
 
/// Represents an error that occurred during an account-related operation.
///
/// Contains:
/// - `message`: a human-readable error description suitable for logging
///   or displaying to the user.
