Round 5 improvements: complete automation and documentation fixes

- Fix password file ownership (user can now read without sudo)
- Add dashboards stack to automated deployment (Step 5/6)
- Add SSL certificate notes to deploy script output
- Clarify .env file location in documentation (stays in repo folder)
- Update README and getting-started.md with accurate deployment steps
- Add Watchtower notification URL documentation
- Improve user feedback with admin credentials and dashboard URLs
- Remove dashboards from 'Next Steps' since it's now automated

User experience improvements:
