test: Add simple test for settings

ref: Move all controller under the same folder

Move all controller to the same folder and rename them to service.

Moving them to the same folder allow an easier setup for testing.

ref: Move away other repositories

Finish moving all repositories to a repository package. This should
reduce the amount of packages.

ref: Refactor how repository is define

To make things easier and reduce the number of package I'll move all
repository to one folder, starting with auth and user repository.

Also implements all testing on top of the repository interface with a im
memory implementation. This will later make mescling unit and
integration easier.

feat: Partially fix test

This will totally be fixed later.

feat: Add initial user setup

feat: Add scheduler to chan processor

feat: Store image size

Add image dimensions to exif fetch.

feat: Add user list UI

Fill user settings UI with actual data.

feat: Add make rules for upx compressing

I don't know if that will work in the long run but I have added just in
case.

fix: Actually read from embedded

Previous implementation was not reading from embedded fs.

feat: Remove bin size

feat: Add mockup for user settings

feat: Add static file to output bin

Now the final binary has a standalone web server including necessary
static file.

feat: Remove unnecessary function

ref: Add itens to TODO

ref: Rename list to batch processor

feat: Add log to list list processor

feat: Add scheduler again

Since I have fixed the issue with the `SIGTINT` hanging the application
I can readd the scheduler once more.

Also move the param for amount of scheduler work.

fix: Wrap media scan into a go routine

For some unknown reason `ReadExif` hangs when the context is canceled
through signal handling. Perhaps perl-exif tooling is closing on
`SIGNINT`.

feat: Remove unecessary param from repo

ref: Remove scratchpad notes

feat: Move params to flags

Start using flags to set some params like key and database connection.
As a flag parse I opt for a lib that uses posix style params.

chore: Add deps

fix: Fix having to login every server reload

fix: Fix linter issues
