Add layout

[MarioRodrigues10]

There's a few things missing in this PR:

• Board index page
• Partner show page
• User settings page
• Change pages config by role in organization
• Organizations index page
• Add a field session_image to an actitivity session
• Add a field logo to an organization
• Fix mobile layout in some pages
• Add news
• Add a field description to a department
• Add a layout to forms
• Fix scanner by role
• Change sidebar depending on user role in an organization
• Fix activities , use (sessions) instead
• Add hook to change default_organization on click (basically now the organization tab is a live_component)
• Add collaborators (many to many user / departments)

A couple of things:

1. On the top left below "CeSIUM" the role shows up as "role". I don't know if you forgot or weren't planning on doing it now, but I think it should be done in this PR
2. I am not a fan of the mobile design. I think we can remove the organization part on top. It is taking up valuable space. When the hamburger menu is clicked, the navbar should take up the entire screen (like we do in CoderDojo Braga, and integrate the organization there
3. We need to add logos for organizations

Although there's an item not done, i made this ready for review , because a member of our team said he wanted to take care of that issue.
