Includes the associated Go functions for inserting and selecting given a
specific user ID or subscription ID. Also adds required HTML tags and
HTTP queries for subscription process during user registration.

To make requests to Go API endpoints for registration from a PHP page,
there needs to be local routing between the two servers. This method
avoids needing Apache installed seperately for development builds while
allowing it to still be used in production if necessary.

Secures the user registration endpoint.

A new template file needed to be created to allow custom javascript in
a grav page. The JS file will mount the transpiled Vue app.

Store only files relevant to the project by tracking only the user/
directory.

At most one result should exist for each loan stored but not redeclaring
the 'estimate' variable within the seed loop caused the loan entries of
the first estimate to be copied onto the second, which caused an error
while seeding result entries.

Also seperate stages of seeding into other functions.

Also structure CLI functions to allow for `skouter dev seed` command.

Summary component was moved to master.tpl because sub-template calls
allow only one argument to be passed. Passing info for both Estimate and
Loan structs dynamically would involve looping during template
execution, or calling a custom function to restructure the estimate,
which are all too complicated.

Split comparison, summary, and header sections into seperate files to
reuse headers more easily and make future changes easier.

Move Result attribute from Estimate to it's related Loan to make it's
meaning less confusing.

the htmltopdf.js library renders all PDF text as images instead of
vectors, and Go does not have a reliable native library for generating
PDFs that is actively maintained. The best solution appears to be to
make a system call to wkhtmltopdf, but now there is a hidden package
dependency that is not checked at build time and exists in another
process. Maybe in the future a C library can be used and linked with the
Go binary.

Using a config file is not necessary and may be confusing.
Also add address and phone number of User and Branch structs.
