## What kind of change does this PR introduce?
Feature. Stack 4 of 5 for
[PIPE-1007](https://linear.app/supabase/issue/PIPE-1007/move-read-replicas-out-of-replication-into-infrastructure).
Contributes to PIPE-1008.
## What is the current behavior?
Database / Replication lists, creates, and diagrams read replicas
alongside pipelines.
## What is the new behavior?
Replication is pipelines-only. No replica rows, type, or diagram nodes.
`?destinationType=Read+Replica` redirects to Infrastructure. A short
callout points create-mode users at the new home.
## Additional context
Please review, but do not merge until
[#48921](https://github.com/supabase/supabase/pull/48921) is ready to
follow immediately. The flag is already on, so this PR is the
user-facing cutover off Replication.
## To test
`infrastructure:read_replicas` is an enabled-feature, on by default.
There is no Feature Preview or ConfigCat switch. You should already see
the Infrastructure Read replicas section. If you do not, your profile
lists `infrastructure:read_replicas` in `disabled_features`.
Open [Database /
Replication](https://studio-staging-git-danny-pipe-1007-04-cut-from-77ef95-supabase.vercel.app/dashboard/project/_/database/replication?destinationType=Read+Replica).
You should land on Infrastructure with the add-replica sheet, not a
replica destination type. The Replication page itself should be
pipelines-only.
