Rebrand from Wrapper API to SAAC API

Changed all references from "Coolify Wrapper" / "WRAPPER_API_KEY" to
"SAAC" / "SAAC_API_KEY" for better branding and user experience.

SAAC = StartAnAiCompany - makes it clear users are deploying to
StartAnAiCompany infrastructure rather than a "wrapper" service.

Changes:
- WRAPPER_API_KEY → SAAC_API_KEY throughout
- "Wrapper API" → "SAAC API" in all documentation
- Updated user-facing messages to reference StartAnAiCompany

This makes the service feel more direct and brand-focused rather
than like a proxy/wrapper layer.
