Why

main fails cargo test --workspace --locked at 825504e. #795's two merged-DDSketch-pane tests in crates/planner/tests/runtime_install.rs were written against the exhaustive search's candidate ids, but #792 (merged just before) made the default search number only the candidates it composes and keep only the first rejection of each cause:

• a_non_negative_gauges_merged_ddsketch_panes_carry_the_relative_bound_through_avg: expects P5-m1, and the same plan is now P3-m1;
• an_undeclared_gauges_merged_ddsketch_panes_get_no_relative_bound_through_avg: expects P5-m1 in the error, and the error now lists P1's RawDataNotRetained.

What

Test-only. The first test no longer asserts the selected id, which depends on how many candidates the search enumerates (P3-m1 today, and fewer with the next joint-search PRs). Its plan, answer and bound checks are unchanged. The second asserts the failure is "no valid candidate" with a RawDataNotRetained rejection.

How

The id assertion is dropped and the error assertion is updated. Nothing else changes.

Key code interfaces added / modified

None (tests only).

Before this PR

On main, cargo test -p asap-planner --test runtime_install: 14 passed, 2 failed.

After this PR

The same command: 16 passed.

Verification

cargo test --locked -p asap-planner --test runtime_install passes. #797 (components) carries the same change.

Superseded by #801, which fixed the same #792 x #795 test breakage on main.
