Save and manage case summaries and context links for each bot individually.

[ERosendo]

The case summary and context link are fields of the Subscription model and are set upon case addition to the database. However, this approach presents a challenge when multiple curators seek to have their respective bots following the same case. In such scenarios, subsequent curators submitting the add-a-case form inadvertently overwrite the values of these fields.

We could consider moving the summary and context link to a separate model to display different data for each bot.
