feat(emailing-domain): add LOG driver for local development (#21286)

## What

Adds a `LOG` driver to the emailing-domain feature, selected via a new
`EMAILING_DOMAIN_DRIVER` config variable (defaults to `AWS_SES`, so
production behavior is unchanged).

The LOG driver:
- resolves domains to `VERIFIED` instantly (no DNS / SES setup)
- logs each `sendEmail` and returns a synthetic `messageId` instead of
calling SES

It also dev-seeds a pre-verified domain per workspace
(`<workspaceId>.dev.twenty.local`) so the feature works out of the box.

## Why

The emailing-domain feature currently ships only the AWS SES driver, so
the verify → send flow can't be exercised locally (or in CI) without
real AWS credentials. This unblocks local development and review of
anything built on emailing domains.

## Usage

```
EMAILING_DOMAIN_DRIVER=LOG
```

The seeded `*.dev.twenty.local` domain is already verified; sends are
logged (`[log-driver] sendEmail ...`).
