## Summary
- Handle malformed selectedFields in the extradata in the migration and
new migration to fix in the already migrated cases.
- Restructure saved-view create/update/get payloads so
`schemaVersion`/`spec` are top-level (unwrapping the old `data`
nesting), matching how dashboards and rules shape their wire types.
- Publish `schemaVersion` as an `enum: [v2]`
- Make `display` and `selectedFields` optional in the OpenAPI schema
- Declare `409` on `CreateSavedView`
- Require `minItems: 1` on `queries`
New API contract in [below

Closes https://github.com/SigNoz/engineering-pod/issues/4651
Notes to reviewer:
- Please pay attention to the last case in above linked comment for
partial display field updates.
- Still assuming that [migration
046](6372af75a6/pkg/sqlmigration/046_update_dashboard_alert_and_saved_view_v5.go (L233))
has already migrated all the views to v5 QB format and don't need to do
that now.
- Breaking change: queries are not validated in the v1 APIs as well, so
any incorrect query will be rejected
