Merge branch 'main' into fts-logs

* feat: add endpoint & module for trace aggregations

* chore: use v1 for aggregations api

* chore: update openapi specs

* feat: add implementation for aggregation store

* chore: use query builder for count by field

* chore: remove support for aggregations on attributes

Only supporting resource fields for now, since this
is not user input but hard coded client experience

* chore: extract out inner query as cte

* chore: again extract out inner query

* chore: move end_ns computation to first cte for simplicity

* chore: use notEmpty function instead of having

* fix: type cast issue in sum function

* chore: use query builder for duration query as well

* chore: add tests for trace store sql

* chore: remove unnecessary column checks

* chore: format the expected sql queries

* fix: formating was breaking test

* fix: change import and remove formating from sql

* chore: remove formating from store impl as well

* fix: mark required fields as required

* fix: explicitly mark nullable false for required field

* fix: mark required fields in response as well

+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.
