refactor: rename SolaceScanScout to Solace and update related configurations

- Updated branding from "SolaceScanScout" to "Solace" across various files including deployment scripts, API responses, and documentation.
- Changed default base URL for Playwright tests and updated security headers to reflect the new branding.
- Enhanced README and API documentation to include new authentication endpoints and product access details.

This refactor aligns the project branding and improves clarity in the API documentation.
