User organizations

[alexculealt]

Implements #21

Implementation stages

Backend

• Add new organizations and memberships tables
• Add organization ID to users and catalogues
• Add migration to seed initial organization & migrate all existing resources (users, catalogues) to this organization
• Adjust all existing data queries (callable APIs) to join intersecting user organizations when selecting information.
• Adjust insert/write/updates to resources to require member organization
• Implement new queries for CRUDing organizations
• Security audit for all accessible resources to ensure proper encapsulation of organizations (RLS)

Frontend

• Add new organization selection screen after authentication
• Add UI org selection drop-down in the header
• Consolidate user state information context to keep user state and selected current active organization viewed
• Adjust all routes to require /org/ in their path
• Ensure tRPC includes current org ID in the context
• Mitigate edge cases (user doesn't have any organizations, organization selected is removed from the user mid session, user tries accessing a link from a resource within an organization that where they don't belong)
• Fix/Verify existing validation test suite
