Add Email Verification for non-Microsoft/Google Emails (#9288)

Closes twentyhq/twenty#8240 

This PR introduces email verification for non-Microsoft/Google Emails:

## Email Verification SignInUp Flow:

https://github.com/user-attachments/assets/740e9714-5413-4fd8-b02e-ace728ea47ef

The email verification link is sent as part of the
`SignInUpStep.EmailVerification`. The email verification token
validation is handled on a separate page (`AppPath.VerifyEmail`). A
verification email resend can be triggered from both pages.

## Email Verification Flow Screenshots (In Order):

### Unsuccessful Email Verification (invalid token, invalid email, token
expired, user does not exist, etc.):

# TODOs:

## Sign Up Process

- [x] Introduce server-level environment variable
IS_EMAIL_VERIFICATION_REQUIRED (defaults to false)
- [x] Ensure users joining an existing workspace through an invite are
not required to validate their email
- [x] Generate an email verification token
- [x] Store the token in appToken
- [x] Send email containing the verification link
  - [x] Create new email template for email verification
- [x] Create a frontend page to handle verification requests

## Sign In Process

- [x] After verifying user credentials, check if user's email is
verified and prompt to to verify
- [x] Show an option to resend the verification email

## Database

- [x] Rename the `emailVerified` colum on `user` to to `isEmailVerified`
for consistency

## During Deployment
- [x] Run a script/sql query to set `isEmailVerified` to `true` for all
users with a Google/Microsoft email and all users that show an
indication of a valid subscription (e.g. linked credit card)
- I have created a draft migration file below that shows one possible
approach to implementing this change:

```typescript
import { MigrationInterface, QueryRunner } from 'typeorm';

export class UpdateEmailVerifiedForActiveUsers1733318043628
  implements MigrationInterface
{
  name = 'UpdateEmailVerifiedForActiveUsers1733318043628';

  public async up(queryRunner: QueryRunner): Promise<void> {
    await queryRunner.query(`
      CREATE TABLE core."user_email_verified_backup" AS
      SELECT id, email, "isEmailVerified"
      FROM core."user"
      WHERE "deletedAt" IS NULL;
    `);

    await queryRunner.query(`
      -- Update isEmailVerified for users who have been part of workspaces with active subscriptions
      UPDATE core."user" u
      SET "isEmailVerified" = true
      WHERE EXISTS (
        -- Check if user has been part of a workspace through userWorkspace table
        SELECT 1 
        FROM core."userWorkspace" uw
        JOIN core."workspace" w ON uw."workspaceId" = w.id
        WHERE uw."userId" = u.id
        -- Check for valid subscription indicators
        AND (
          w."activationStatus" = 'ACTIVE'
          -- Add any other subscription-related conditions here
        )
      )
      AND u."deletedAt" IS NULL;
  `);
  }

  public async down(queryRunner: QueryRunner): Promise<void> {
    await queryRunner.query(`
      UPDATE core."user" u
      SET "isEmailVerified" = b."isEmailVerified"
      FROM core."user_email_verified_backup" b
      WHERE u.id = b.id;
    `);

    await queryRunner.query(`DROP TABLE core."user_email_verified_backup";`);
  }
}

```
