Enable document model in sycamore.query + query-ui improvements

[baitsguy]

A few changes all over to support doc model and usability for sycamore query.

1. Use document model in sycamore.query by enabling reconstruct_document in db scans and use_elements in llm map ops
2. Allow custom properties in extract_entity when use_elements is True
3. Write LogicalPlan in SycamoreExecutor when trace_dir provided
4. Query UI updates to support local mode, view query plan in TraceViewer. Local mode will only work for query plans that are runnable on local_mode

note: The queries have only been manually tested so it's possible we'll have to make more changes. Might need UI changes if we want to show/highlight elements within a doc that passed a filter/opensearch query
