Initial commit: Buildfor Life Budget app

Multi-company budget/project tracking tool built with SvelteKit 5,
PostgreSQL (Drizzle ORM), and Tailwind CSS v4.

Features:
- Auth: local (email/password with Argon2) + generic OIDC
- 4 roles per company: admin, manager, user, viewer
- Multi-company with per-company user membership
- Projects with budget allocation from company pool
- Expense submission with approval workflow
- Categories and tags for expense organization
- Reports with spending breakdowns (by category, project, time)
- CSV import for Actual Budget migration
- Company audit log tracking all budget and admin actions
- Remaining budget hero display on overview and budget pages
- Admin-only company creation; new users wait for invitation
- Deployment configs for systemd + nginx (bare metal/Proxmox)
