fix(): sleep before redirect (#9079)

## 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.
