feat(weave): scorer_* typed columns on feedback

[nikumar1206]

Description

Wires the four `scorer_*` columns from #6906 through the trace-server so they round-trip via the existing feedback endpoints.

• `orm.py`: new column types `array_string`, `map_string_string`, `map_string_float`. ClickHouse passes native list/dict; SQLite encodes as JSON text and decodes on read.
• `feedback.py`: adds the four columns to `TABLE_FEEDBACK`. `format_feedback_to_row` defaults `None` → `[]` / `{}`.
• `trace_server_interface.py`: four optional fields on `FeedbackCreateReq` (inherited by `Feedback` / `FeedbackReplaceReq`).

Testing

Unit tests.

One comment to address, otherwise LGMT.

Let's not merge this until after the migration has been deployed just in case.
