Add the company relation and read-only form to edit
I do not have more time to update the update to the company today, but i
believe this is already a good amount of work for a commit.
The company is going to be used for row level security, as users will
only have access to the data from companies they are granted access, by
virtue of being in the company_user relation.
I did not know how add a row level security policy to the company_user
because i needed the to select on the same relation and this is not
allowed, because it would create an infinite loop.
Had to add the vat, pg_libphonenumber, and uri extensions in order to
validate VAT identification numbers, phone numbers, and URIs,
repectively. These libraries are not in Debian, but i created packages
for them all in https://dev.tandem.ws/tandem.

Convert from cents to “price” and back
I do not want to use floats in the Go lang application, because it is
not supposed to do anything with these values other than to print and
retrieve them from the user; all computations will be performed by
PostgreSQL in cents.
That means i have to “convert” from the price format that users expect
to see (e.g., 1.234,56) to cents (e.g., 123456) and back when passing
data between Go and PostgreSQL, and that conversion depends on the
currency’s decimal places.
At first i did everything in Go, but saw that i would need to do it in
a loop when retrieving the list of products, and immediately knew it was
a mistake—i needed a PL/pgSQL function for that.
I still need to convert from string to float, however, when printing the
value to the user. Because the string representation is in C, but i
need to format it according to the locale with golang/x/text. That
package has the information of how to correctly format numbers, but it
is in an internal package that i can not use, and numbers.Digit only
accepts numeric types, not a string.

Split contact relation into tax_details, phone, web, and email
We need to have contacts with just a name: we need to assign
freelancer’s quote as expense linked the government, but of course we
do not have a phone or email for that “contact”, much less a VATIN or
other tax details.
It is also interesting for other expenses-only contacts to not have to
input all tax details, as we may not need to invoice then, thus are
useless for us, but sometimes it might be interesting to have them,
“just in case”.
Of course, i did not want to make nullable any of the tax details
required to generate an invoice, otherwise we could allow illegal
invoices. Therefore, that data had to go in a different relation,
and invoice’s foreign key update to point to that relation, not just
customer, or we would again be able to create invalid invoices.
We replaced the contact’s trade name with just name, because we do not
need _three_ names for a contact, but we _do_ need two: the one we use
to refer to them and the business name for tax purposes.
The new contact_phone, contact_web, and contact_email relations could be
simply a nullable field, but i did not see the point, since there are
not that many instances where i need any of this data.
Now company.taxDetailsForm is no longer “the same as contactForm with
some extra fields”, because i have to add a check whether the user needs
to invoice the contact, to check that the required values are there.
I have an additional problem with the contact form when not using
JavaScript: i must set the required field to all tax details fields to
avoid the “(optional)” suffix, and because they _are_ required when
that checkbox is enabled, but i can not set them optional when the check
is unchecked. My solution for now is to ignore the form validation,
and later i will add some JavaScript that adds the validation again,
so it will work in all cases.

Split contact relation into tax_details, phone, web, and email
We need to have contacts with just a name: we need to assign
freelancer’s quote as expense linked the government, but of course we
do not have a phone or email for that “contact”, much less a VATIN or
other tax details.
It is also interesting for other expenses-only contacts to not have to
input all tax details, as we may not need to invoice then, thus are
useless for us, but sometimes it might be interesting to have them,
“just in case”.
Of course, i did not want to make nullable any of the tax details
required to generate an invoice, otherwise we could allow illegal
invoices. Therefore, that data had to go in a different relation,
and invoice’s foreign key update to point to that relation, not just
customer, or we would again be able to create invalid invoices.
We replaced the contact’s trade name with just name, because we do not
need _three_ names for a contact, but we _do_ need two: the one we use
to refer to them and the business name for tax purposes.
The new contact_phone, contact_web, and contact_email relations could be
simply a nullable field, but i did not see the point, since there are
not that many instances where i need any of this data.
Now company.taxDetailsForm is no longer “the same as contactForm with
some extra fields”, because i have to add a check whether the user needs
to invoice the contact, to check that the required values are there.
I have an additional problem with the contact form when not using
JavaScript: i must set the required field to all tax details fields to
avoid the “(optional)” suffix, and because they _are_ required when
that checkbox is enabled, but i can not set them optional when the check
is unchecked. My solution for now is to ignore the form validation,
and later i will add some JavaScript that adds the validation again,
so it will work in all cases.

Add the company relation and read-only form to edit
I do not have more time to update the update to the company today, but i
believe this is already a good amount of work for a commit.
The company is going to be used for row level security, as users will
only have access to the data from companies they are granted access, by
virtue of being in the company_user relation.
I did not know how add a row level security policy to the company_user
because i needed the to select on the same relation and this is not
allowed, because it would create an infinite loop.
Had to add the vat, pg_libphonenumber, and uri extensions in order to
validate VAT identification numbers, phone numbers, and URIs,
repectively. These libraries are not in Debian, but i created packages
for them all in https://dev.tandem.ws/tandem.
