ref(integrations): Remove the legacy web-view setup pipeline from integrations

Every integration provider now installs through the API-driven pipeline
(`get_pipeline_api_steps()` + the organization pipeline endpoint), so the
server-rendered web-view setup path is dead for integrations.

Drop `get_pipeline_views()` from the `IntegrationProvider` base class and
from all provider subclasses (each was a no-op `return []`).
`IntegrationPipeline` now returns an empty list of pipeline views directly,
so integration pipelines no longer depend on the provider method.

Delete the now-unused `OrganizationIntegrationSetupView` and its
`/extensions/<provider>/setup/` route, plus the dangling test helper.

The generic `Pipeline` framework (and `PipelineView`/`PipelineAdvancerView`)
is left intact since it is still shared with the auth/SSO and identity
pipelines.
