feat: Add build pieces

Adding pieces to be able to later build to alpine

ref: Move the yt manager to the worker

Simplify the worker/manager relationship. Now the worker is responsible
for the managing the yt-dlp process as well.

Also introduce chan to report back logs. That is an attempt to decouple
things.

feat: Add custom css

ref: Remove model dependency fom worker

It was a bit weird to have that dependency in first place.

ref: Make the slice at once

A small optimization, it will create the slice at once so it won't to
expand multiple time later when append is called.

fix: Pass entry as reference

It was not getting the object created by gorm so `.ID` was 0 causing all
sort of weird iterations.

That is also cause by the lack of testes. That will also be fixed in the
next commits.

feat: Add one more state

Add a new state to the worker so it can better report what is happening.
Also added a status report in the index page.

feat: Add gitlab pipeline

feat: Add worker

Add a simple worker to manage a work queue. Right now, it is bit
brittled and has no test coverage yet, but it works.

Also moved from pico.css to bulma, I like the idea of classes approach
of pico but for me bulma yields a better result.

ref: Move to a MVC like approach

Before everything was dumped into the controller file, now it is spread
out a bit.

It is still far from good, like the controller is not really a
controller... baby steps I guess

The refactored was based on this post:

ref: Rename snake case variable

My pythonic brain kicked in and I ended up naming a variable using snake
case.

feat: Add poor implementation for the worker

This is just me testing a bit how doworker works, while I learn of
go/gin in the process.
