Anonymise customer first and last names

[dacook]

These were added a couple of years ago in #8763 But I guess we never noticed the names weren't getting anonymised.

The old 'name' field is still in the DB. It was kept for compatibility during migraiton but never cleaned up. I've added the tech debt task to the welcome new devs board now: #8835

What should we test?

Run the script and check that customer names can not be viewed in the system.

This must be executed on uk_staging because it was recently refreshed from prod and the customer names will still be present. IE:

ssh [email protected]
cd apps/openfoodnetwork/current
RAILS_ENV=staging bundle exec rake ofn:data:anonymize

Testing on fr_staging

Before: real customer names appeared in Admin > Customers (not shown here for privacy reasons of course).

I ran the updated queries directly and it worked:

irb(main):020:0>       Customer.where(user_id: nil)
irb(main):021:1"         .update_all("email = concat(id, '[email protected]'),
irb(main):022:1"                      name = concat('Customer Number ', id, ' (without connected User)'),
irb(main):023:1"                      first_name = concat('Customer Number ', id),
irb(main):024:1"                      last_name = '(without connected User)'")
=> 12744
irb(main):025:0>       Customer.where.not(user_id: nil)
irb(main):026:1"         .update_all("email = concat(user_id, '[email protected]'),
irb(main):027:1"                      name = concat('Customer Number ', id, ' - User ', user_id),
irb(main):028:1"                      first_name = concat('Customer Number ', id),
irb(main):029:1"                      last_name = concat('User ', user_id)")
