chore: align migrations, docs, and frontends with crewli.app setup

- Replace dated migrations with ordered 2026_04_07_* chain; fold users update into base migration
- Update OrganisationScope, AppServiceProvider, seeders, api routes, and .env.example
- Refresh Cursor rules, CLAUDE.md, Makefile, README, and docs (API, SCHEMA, SETUP)
- Adjust admin/app/portal HTML, packages, api-client, events types, and theme config
- Update docker-compose and VS Code settings; remove stray Office lock files from resources

Made-with: Cursor
