Merge POST /accounts/verify/:token into PATCH /accounts/:id

[lautarodragan]

It's just an update to the account after all.

The only special thing about it is the authorization - it requires a special token.

if (body.verified && tokenData.meta.name !== Token.VerifyAccount.meta.name) {
  logger.warn({ account, tokenData }, 'User tried to verify email with incorrect token type.')
  throw new Unauthorized()
}

It can be done in different steps to avoid breaking anything:

• Add functionality to PATCH /accounts
• Make changes in Explorer
• Remove deprecated endpoint
