Eliminated all references to `isSSOEnabled` across the frontend,
backend, and configuration files. This change simplifies the codebase by
removing unnecessary feature flag checks, associated logic, and
environment variables. The SSO feature remains available without
reliance on this flag.
## Summary
This Pull Request centralizes the redirection logic by introducing a
reusable `useRedirect` hook, which replaces direct usage of
`window.location.href` with more standardized and testable functionality
across multiple modules.
- Introduced a new `useRedirect` hook for handling redirection logic
with optional controlled delays.
- Refactored redirection implementations in various modules (`useAuth`,
workspace, and settings-related hooks, etc.) to use the newly introduced
`useRedirect` or related high-level hooks.
- Updated API and documentation to include or improve support for SSO,
particularly OIDC and SAML setup processes in server logic.
- Enhanced frontend and backend configurability with new environment
variable settings for SSO.
