jordi fita mas 9e757cb9f4 Show the profile form in a dialog using HTMx
Had to split the actual page content and the breadcrumbs because they
do not belong in a dialog.  However, i had to change all templates to
do that.

jordi fita mas 8efae0485e Add the edit form for invoices
I had to change the way /invoices/new and /invoices/batch are handled,
because httprouter was not happy with the new POST /invoices/:slug/edit
route, claiming that /invoices/:slug conflicts with the previously
existing routes.

I also could not make it work with the PATCH method, even though i
correctly added the patchMethod override function, therefore editing
invoices is also weird because i have to take into account the “quick”
invoice status change.

I use the same form for both new and edit invoices, because the only
changes are that we can not edit the invoice date and number, by
Oriol’s design, but must be able to change the status; very similar
forms.

jordi fita mas 0c8edb9cae Add option to duplicate an invoice
With Oriol we agreed that a duplicate is just the new invoice form
prefilled with the data from another invoices, but without the number or
the date.

jordi fita mas d6034ad732 Add discount and tax classes columns to invoice
This was actually the (first) reason we added the tax classes: to show
them in columns on the invoice—without the class we would need a column
for each tax rate, even though they are the same tax.

The invoice design has the product total with taxes at the last column,
above the tax base, that i am not so sure about, but it seems that it
has not brought any problem whatsoever so far, so it remains as is.

Had to reduce the invoice’s font size to give more space to the table
or the columns would be right next to each other.  Oriol also told me
to add more vertical spacing to the table’s footer.

jordi fita mas 4d2379555e Convert invoices to PDF with WeasyPrint
Although it is possible to just print the invoice from the browser, many
people will not even try an assume that they can not create a PDF for
the invoice.

I thought of using Groff or TeX to create the PDF, but it would mean
maintaining two templates in two different systems (HTML and whatever i
would use), and would probably look very different, because i do not
know Groff or TeX that well.

I wish there was a way to tell the browser to print to PDF, and it can
be done, but only with the Chrome Protocol to a server-side running
Chrome instance.   This works, but i would need a Chrome running as a
daemon.

I also wrote a Qt application that uses QWebEngine to print the PDF,
much like wkhtmltopdf, but with support for more recent HTML and CSS
standards.  Unfortunately, Qt 6.4’s embedded Chromium does not follow
break-page-inside as well as WeasyPrint does.

To use WeasyPrint, at first i wanted to reach the same URL as the user,
passing the cookie to WeasyPrint so that i can access the same invoice
as the user, something that can be done with wkhtmltopdf, but WeasyPrint
does not have such option.  I did it with a custom Python script, but
then i need to package and install that script, that is not that much
work, but using the Debian-provided script is even less work, and less
likely to drift when WeasyPrint changes API.

Also, it is unnecessary to do a network round-trip from Go to Python
back to Go, because i can already write the invoice HTML as is to
WeasyPrint’s stdin.

jordi fita mas 419ac3ed46 Adjust invoice.css to work with WeasyPrint too
I am planning to use WeasyPrint to “generate PDF” from the same HTML
that the user view, but it seems that it does not support flex’s gap
and some other properties that i had to change to work in both user
agents.

I also moved the invoice’s “footer” inside the last product’s body
because i do not want the footer to be a “widow”.

jordi fita mas 18fba2964f Add invoice view, with print CSS
Had to group name and description rows in tbody because i do not want
to break them on pagination.

I also could not use tfoot for subtotal, taxes, and total because then
they appear on every page.

The disclaimer should appear only at the very bottom of the last page,
but i do not know how to do that; using position fixed shows it on
every page.
