## What kind of change does this PR introduce?
Studio UI refactor.
## What is the current behavior?
Pipeline table reset dialogs repeat explanatory content and use more
layout than the reset decision needs.
## What is the new behavior?
Simplifies the single-table and batch reset confirmations while
preserving their cost estimate, destructive consequences, and existing
reset mutations.

## To test
1. Open `/project/<ref>/database/replication` and select a pipeline.
2. Reset one replicated table and confirm the dialog explains that
destination data will be deleted and resynchronised.
3. Choose **Reset all tables** and confirm the batch dialog shows the
same concise treatment.

## UI Updates
* **UI Updates**
* Renamed replication “restart” actions to “reset” across dialogs,
buttons, notifications, and cost estimates.
* Updated messaging to clarify whether the pipeline will start or
restart automatically after resetting.
* Added clearer initial-sync guidance for all, some, or none of the
affected tables.
* Improved reset cost estimate messaging, including when no additional
initial-sync charge applies.
* Updated reset dialogs with clearer titles, descriptions, loading
states, and error messages.
* Disabled reset actions when pipeline status is unavailable.

## 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.
