Simplify enum classes

[andregasser]

As outlined here, enum classes can be simplified. Instead of writing code like this:

enum class SourceSuggestion(val value: String) {
    STAFF("staff"),
    PAST_INTERACTIONS("past_interactions"),
    GLOBAL("global")
}

we can write code like so:

@Serializable
enum class SourceSuggestion {
    @SerialName("staff")
    STAFF,

    @SerialName("past_interactions")
    PAST_INTERACTIONS,

    @SerialName("global")
    GLOBAL
}

Doing so we let the serializer do the translation work for us and we can simplify the constructor.

All the enum classes in the project should be reviewed and simplified if it makes sense.

Assign me this, so that I will try to refactor any enum used within any dto model

[G10xy]

Let's take in consideration the Enum CardType, for example. This enum was made to restrict the possible values for the attribute "type" of the PreviewCard dto model.
Should I update the "type" attribute as Type
@SerialName("type") val type: CardType = CardType.Link,

or remain it as String?
@SerialName("type") val type: String = CardType.Link.name.lowercase(),

Hello @G10xy I'd switch this to type CardType.
