feat: v0.3.0 — standardize codebase, centralize infra, merge QR into CMS

- Enforce axum best practices across all 13 workspace crates
  (max 200 LOC/file, no comments, no unwrap, clean architecture)
- Fix domain→infrastructure dependency inversions in imphnen-iam and imphnen-dimentorin
- Extract imphnen-storage (MinIO) and imphnen-email (Lettre) as standalone crates
- Centralize all config in ENV struct: CDN_URL, CORS_ALLOWED_ORIGINS
- Centralize SMTP through imphnen-email; remove dead HackathonConfig
- Centralize database: QR crate now shares main DB pool (single DATABASE_URL)
- Rename QR users table to qr_users to avoid collision with main users table
- Merge imphnen-qr into imphnen-cms/src/qr (13 crates, down from 14)
- Restructure imphnen-hackathon flat modules into clean architecture
- Remove all stale env vars from .env.example (SurrealDB, QR_JWT, Hackathon infra)
- Fix Dockerfile to include all current workspace crates
- Bump all crate versions 0.2.0 → 0.3.0
