feat(logs): show query and details in unified PG log dashboards DEBUG-138 (#47026)

## Problem

The unified log dashboards' Postgres detail panel hid the `query` and
`detail` fields. They were present in the raw log message but never
surfaced in the structured view, making them harder to use when
debugging.

## Fix

- Select `pgl_parsed.query` and `pgl_parsed.detail` in the Postgres
service flow query.
- Add `Query` and `Details` field configs to the Postgres primary
fields, both with `wrap: true` so long values display in full instead of
truncating.

The parsed Postgres field is `detail` (singular); it is labeled
"Details" in the UI.

## How to test

- Open Studio and navigate to the unified logs dashboard for a project.
- Filter to Postgres logs and select a log row to open the detail panel.
- Confirm the Postgres section now shows `Query` and `Details` rows
below `User`.
- Expected result: rows render the parsed query and detail text,
wrapping for long values, and show an em dash when empty.

## Summary by CodeRabbit

* **New Features**
* PostgreSQL service flow logs now show additional always-visible
**Query** and **Details** fields, bringing parsed database query content
and expanded information directly into the log view.
* **Tests**
* Updated log inspection coverage to ensure the new parsed fields are
correctly surfaced in the flattened inspection output.
