Instead of adding all routes manually in the Launch function for Rocket,
implement fairings for all the different files that adds the routing to
the rocket in a self-contained manner.
Previously, most redirects targeted the root of the application.
This was okay for the first part of development where only one week would be
active, but would be annoying when using multiple weeks.
Change those redirects to call week::week.
Change the login path to be dependant on the current week as well,
so it can be correctly redirected.
Implement a way for admins to introduce new weeks and set them as the last active one.
The last active week is the last one that is accessible to players, and will also prevent
the graph from being displayed.
Implement arrows for navigating between the weeks in the HTML.
- Create a new migration adding a Weeks table, allowing for new weekly introductions
and paving the way for multiple week handling.
- Add route to update the weekly introduction
- Move the week rendering to a specific week file
- Update the templates to use the week number from the week data
- Update templates to render and edit weekly introductions
