Remove all Coolify branding, replace with StartAnAiCompany

Users should see this as the "StartAnAiCompany platform" not as a Coolify proxy.

Changes:
- README.md: "StartAnAiCompany infrastructure" and "StartAnAiCompany platform"
- DEPLOYMENT_GUIDE.md: Removed all Coolify references
- deploy-to-apps.example.sh: "deployment platform" instead of "Coolify"

Now all user-facing documentation uses StartAnAiCompany/SAAC branding exclusively.
