Update deployment to use vadym.samoilenko user

Changed deployment user from www-data to vadym.samoilenko across all configuration files. Added permission checks and automatic chmod/chown in deploy script.

Changes:
- deploy.sh: Check user exists, set ownership to vadym.samoilenko, add chmod
- systemd service: Run as vadym.samoilenko
- DEPLOY.md: Updated all references to vadym.samoilenko
- .env.example: Updated default user
