fix(reporter): stop test-origin bullets gluing onto the cost line

[veksen]

What

In the CI PR comment, the test-origin queries excluded from the gate list rendered the second query on the same line as the first query's cost label:

SELECT "id", ... FROM "sessions" LIMIT 50;
cost 1- SELECT "id", ... FROM "item_watches" LIMIT 50;
cost 1

Why

The template engine is configured with trimBlocks: true (github.ts), which strips the newline immediately after a block tag. The test-origin row ended with a trailing {% endif %}, so that newline got eaten and the next - bullet glued onto the previous item's cost line. Every other row in this template already guards against this by appending {{""}} after the trailing {% endif %} — this section was the only one missing it.

Fix

Append the same {{""}} guard so the block tag is no longer the last token on the line and the newline survives.

Test

Added a regression test that renders two excluded queries and asserts each starts its own bullet. Verified it fails without the fix (reproduces cost 1- <code>…) and passes with it.
