refactor(qb): build IN as an OR of equalities

The IN and NOT IN cases route each value back through the condition builder
with `=` / `!=`, instead of assembling the comparisons themselves. Whatever a
builder does for a scalar comparison then applies to the list form without
being restated.

Applied to logs, traces, audit and resourcefilter, which all fanned a list out
into per-value comparisons already. Metrics and rulestatehistory build a real
sb.In, so there is nothing to delegate to. telemetrymetadata is left alone as
well: it applies a key-existence guard at a single exit, so a recursed arm
comes back already wrapped, and either the guard nests or the case has to skip
the shared tail and lose the invariant that every case is guarded.

This fixes `body.<path>[*] IN [...]` with use_json_body off, which returned a
500. The list shape made the path extract as Array(String), and comparing that
to each scalar is something ClickHouse rejects outright (code 130); extracting
per value reads the field instead. Covered end-to-end by the new case in
querierlogs/06_json_body.py, which fails on main and passes here.

resourcefilter changes shape without changing results: each value is paired
with its own index filter — `(e1 AND k AND l1) OR (e2 AND k AND l2)` rather
than `(e1 OR e2) AND k AND (l1 OR l2)` — which selects the same rows because
each equality implies its own filter.
