Brandon Hopkins df39c2b254 [infrastructure] Deprecate legacy Dex and Zitadel getting-started scripts (#6952)
## Describe your changes

Retire the legacy Dex and Zitadel installation scripts by replacing
their implementations with compatibility notices that:

- Exit unsuccessfully before making any system changes.
- Direct new deployments to `getting-started.sh` and the self-hosting
quickstart.
- Explain that the current installer uses NetBird's embedded Dex-based
identity provider.
- Direct users to configure Zitadel through the NetBird Dashboard or
follow the advanced guide for a standalone identity-provider deployment.
- Clarify that Dex support, Zitadel support, and existing deployments
are not deprecated.
- Announce that the compatibility notices will be removed in NetBird
v0.80.

Replace the legacy Zitadel provisioning workflow with CI checks that
verify both scripts fail, write their notices to stderr, and include the
expected documentation links and removal version.
