+Full-text search integration tests — context isolation.

+Validates that FTS (bare text, "quoted", search()) correctly finds logs
+when the search term lives in any one of the intended field contexts:
+
+    severity_text       — LowCardinality(String), LOWER/match
+    trace_id            — String, LOWER/match
+    span_id             — String, LOWER/match

+    attributes_number   — Map(String,Float64), arrayExists(match, mapKeys)
+    resources_string    — Map(String,String), arrayExists(match, mapKeys/mapValues)
+
+Each test log carries a unique token in exactly one context; all other fields
+are neutral.  Per-context assertions verify:
+    1. Exactly 1 row is returned (isolation — no cross-context bleed).
+    2. The returned row belongs to the expected log (service.name check).
+    3. The FTS warning is always present in the response.

+Each test log carries a unique token in exactly one context; all other fields
