Remove dry-run feature and update email configuration

Changes:
- Remove DRY_RUN environment variable and --dry-run CLI flag
- Always send emails directly without preview mode
- Update sender email to x-news@ksalk.pl
- Remove dry run config from types, env schema, and email service

Email now successfully sends to konrad.salkowski@gmail.com from x-news@ksalk.pl
