fix(angular-db): config-object input to injectLiveQuery now syncs (#1638)

The `{ query }` config-object branch called createLiveQueryCollection(opts)
without defaulting startSync, unlike the query-fn and reactive-options branches
(which force startSync: true). A bare `{ query }` therefore never synced and
returned empty. Default startSync: true and gcTime: 0 while honoring explicit
values in the config.

Clears the angular-db conformance knownGap (config-object-input).

+fix(angular-db): a `{ query }` config-object passed to `injectLiveQuery` now syncs
+
+The config-object branch called `createLiveQueryCollection(opts)` without defaulting `startSync`, unlike the query-function and reactive-options branches (which force `startSync: true`), so a bare `{ query }` never started syncing and produced no data. It now defaults `startSync: true` and `gcTime: 0` while still honoring any explicit values in the config.
