Before this PR, the changed tests would overwrite the entire `tenant_config` because `pageserver_config_override` is merged non-recursively into the `ps_cfg`. This meant they would override the `PAGESERVER_DEFAULT_TENANT_CONFIG_COMPACTION_ALGORITHM`, impacting our matrix build for `compaction_algorithm=Tiered|Legacy` in https://github.com/neondatabase/neon/pull/7748. I found the tests fixed in this PR using the `NEON_PAGESERVER_PANIC_ON_UNSPECIFIED_COMPACTION_ALGORITHM` env var that I added in #7748. Therefore, I think this is an exhaustive fix. This is better than just searching the code base for `tenant_config`, which is what I had sketched in #7747. refs #7749
