Subject: feat: Add initial skeleton for ModsView (#27)

* feat: Backend code to get list of installed mods

For now simply parses `enabledmods.json`.
Note that this file will not be up-to-date if the user just installed a
mod but hasn't launched Northstar yet.

* feat: Empty skeleton page for ModsView

Will be populated later with list of installed mods

* chore: Remove leftover print statement
