Resolves [Dependabot Alert 289](https://github.com/twentyhq/twenty/security/dependabot/289) and a couple other alerts. Removed types for `imapflow` since the package ships them internally now. `yarn.lock` has major changes due to an upgraded AWS SDK `@aws-sdk/client-sesv2` which is used by Nodemailer 7. - No breaking changes were introduced in imapflow and mailparser. - Nodemailer's breaking change was dropping the legacy SES transport; we already use the SMTP transport + our own AWS SES client, so nothing else needs changing.
