fix: testnet deploy path + postgres db-init permissions

- Move testnet deploy path from /home/ubuntu/ to $HOME/ (JOY user)
- Remove sudo from cp commands (no longer needed)
- Fix Caddyfile naming (Caddyfile → Caddyfile-testnet to match compose mount)
- Fix frontend env naming (→ common-frontend-testnet.env to match compose)
- Fix db-init chown UID from 2000 to 999 (postgres user)
