Technical Description

This PR adds a "My Team" checkbox filter to the email template selection modal for engagements. It also resolves an issue with attaching users because of a newly introduced json column to the users table. See the following for reference: filamentphp/filament#8698, https://www.postgresql.org/docs/current/datatype-json.html

We may want to use jsonb as the column type in other situations as well, to avoid this issue elsewhere in the future.
