Refactor

[magnulei]

Main reason for refactoring

Move away from ui_pages.py and ui_server.py and replace it with a separate python modules for each page in the app.
Makes it easier to add new pages or edit existing ones.

Also, manage the project with uv?

Also, maybe implement Tapyr Python framework

Also, maybe making some interavtive plots?

I think the latest iTables now support using data only from selected rows, enabling some cool interactive plotting for the sequencing tab.

plot with this maybe?:

Basically all done in latest updates.

modules refactoring in this PR: #14

Interactive plots for the sequencing tab will have to wait. It could work if using an iTable widget (which now has support for returning data from selected rows), but the widget has many other issues that make stuff strange. But with the selection feature it is easier to copy the data needed and draw the plot in excel when needed. So I think we leave it with that until we can have data return from the DT table.
