PR Review: chore: fix tests

Overall this is a clean set of test fixes adapting to updated KV and workflow APIs. Changes are well-scoped and the intent is clear.

---

Issues

1. .unwrap() instead of ? in kv_operations.rs (tests 11 and 13)

Two estimate_kv_size calls use .unwrap() despite the test function returning Result. Using ? would give a proper error message on failure. All other fallible calls in these tests consistently use ?.

// Current (kv_operations.rs:259-262)
let size = db
    .run(|tx| async move { kv::estimate_kv_size(&tx, actor_id).await })
    .await
    .unwrap(); // should be ?

// Better
let size = db
    .run(|tx| async move { kv::estimate_kv_size(&tx, actor_id).await })
    .await?;

2. standalone() generates a new ID on every call

Id::new_v1(self.config.dc_label()) in the new TestCtx::standalone() generates a fresh UUID on each invocation. If a test calls it more than once expecting a stable dc_id, it will get different IDs each time. Consider storing the dc_id on TestCtx or accepting it as a parameter, similar to how ray_id is handled.

---

Minor Notes

• namespace_id in the test Recipient structs is a fresh random ID unrelated to any actual namespace — fine for tests since the field is only used for billing metrics.
• The VersionCheck → Branch rename in cursor.rs is a straightforward test fix with no concerns.
• The metadata field change from create_ts to update_ts correctly tracks the production struct, which now only exposes update_ts in KvMetadata.
