Update DB Schema migration scripts for Sentry integration
Add schema migration steps
Sentry integration DB/ORM level (no actual log in yet)
Update unit tests (Need to add tests to filter data on user level)
Added authorization and authentication for /admin/* routes

- Authentication is done by a HTML login form
- Authorization is done by setting permissions for groups of routes (for now using a regex as permission key)
- Admin routes have been grouped into an /admin group, authentication is checked in Route middleware on this group
Reorganize Admin templates into nested templaes (allows reuse of most of the template)
Prefix api routes with /api
Add admin routes for basic user management
Add HTTP Basic authentication to all /api routes
Small formatting fixes
Redirect root (/) to /admin
Allow authorization headers
