docs(platforms): query logs via the ClickHouse endpoint (#49299)

The `logs.all` Management API endpoint runs BigQuery SQL and is being
retired next month. The Platforms guide was the only hand-written doc
still pointing at it.

Repoints the debugging example at `GET
/v1/projects/{ref}/analytics/endpoints/logs`, which serves the same data
as a single `logs` table keyed by `source`, with structured fields in
the `log_attributes` map, and converts the query to the ClickHouse
dialect.

Verified by running the example's exact SQL and curl shape against a
real project on the OTEL logs endpoint: 100 rows, with `status_code` and
`path` populated.

The generated API specs still list `logs.all`; those regenerate from the
platform side.

 When you need to debug a project, you can query the project's logs to see if there are any errors and address them accordingly.
 
+Every log line from every service is a row in a single `logs` table, so filter by the `source` column to pick a service. Structured fields live in the `log_attributes` map, and the SQL is the ClickHouse dialect.
