feat: add SSO environment variable support for OKTA and Google OAuth2

Add native support for SSO configuration through environment variables
and Docker secrets, eliminating the need to modify configuration.py
for common SSO providers.

Changes:
- Add OKTA OpenID Connect configuration variables:
  - SOCIAL_AUTH_OKTA_OPENIDCONNECT_KEY (env var)
  - SOCIAL_AUTH_OKTA_OPENIDCONNECT_SECRET (env var + Docker secret: okta_openidconnect_secret)
  - SOCIAL_AUTH_OKTA_OPENIDCONNECT_API_URL (env var)

- Add Google OAuth2 configuration variables:
  - SOCIAL_AUTH_GOOGLE_OAUTH2_KEY (env var)
  - SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET (env var + Docker secret: google_oauth2_secret)

Follows existing patterns with _read_secret() for sensitive data and
environ.get() for non-sensitive configuration.

Resolves: #1139
