UUID everywhere: all API URLs use ID instead of slug

- /projects/{project_id} instead of /projects/{slug}
- /members/{member_id} instead of /members/{slug}
- /projects/{project_id}/files/* instead of /projects/{slug}/files/*
- /projects/{project_id}/members/* instead of /projects/{slug}/members/*
- create_task: ?project_id= instead of ?project_slug=
- list_tasks: removed project_slug filter (use project_id)
- addProjectMember: accepts member_id in body
- Heartbeat timeout: lookup by Member.id
- Slug remains only for: display, uniqueness check, login form
