## Summary
Adds initial-copy scoping to Pipelines in Studio. Users can copy all
existing rows, skip all initial copies, copy only selected publication
tables, or skip selected table copies. All publication tables continue
streaming new changes regardless of the initial-copy policy.
The policy now round-trips through create, edit, validation, and the
generated Management API contract. Initial-copy estimates and
table-restart confirmations use the same scope. Edit requests also
preserve redacted credentials and pipeline settings that Studio does not
own.
This completes the Studio layer of the [ETL API
change](https://github.com/supabase/etl/pull/897) and [Management API
change](https://github.com/supabase/platform/pull/35479).

## Summary by CodeRabbit
- **New Features**
- Added configurable “initial table copy” policies (copy/skip all and
copy/skip selected) during replication setup, including table-picker
behavior, pruning of stale selections, and updated restart/cost
estimates.
- **Bug Fixes**
- Improved restart flows to consistently use `schema.table` identity and
simplified “errored tables” targeting to match error-state tables.
- Reduced unnecessary loading by gating publication/table fetches to
when panels are visible; improved validation/toast handling when
publication tables are unavailable.
- **Tests**
- Added/expanded coverage for destination form submission, table-copy
selection, restart/cost dialogs, and copy-estimate summarization.
- **Style**
- Refreshed warning/label text for clearer configuration and
confirmation messaging.

This PR improves the replication UI in the following ways:
- Adds a new selecion picker for destinations which is split by the
destination location and it's clearer and can scale more when we add
more destinations.
- Adds a much improved section on lag, highlighting new metrics that
could help debug issues more easily.
- Improves the copy across the whole code.
- Fixes the 2d topological view of replication with better status
handling.
