Use ChangeIndexer.deleteAllForProject on project deletion

When a project is deleted, all its changes must be removed from the
index. The plugin previously iterated over write indexes and called
ChangeIndex.deleteAllForProject() directly. This bypassed the higher-
level API and duplicated index selection logic.

Route the deletion through ChangeIndexer.deleteAllForProject(), which:
- Centralizes index handling across backends and shards.
- Emits the onAllChangesDeletedForProject notification for listeners.
- Simplifies the code by removing the local iteration helper.

This aligns the plugin with the API introduced in I4c8a53629 and avoids
the pitfalls of calling low-level ChangeIndex operations directly.

Note: this partially re-applies reverted I7a171837bca, without the
provided notification via stream events, which was not correct.
