test(proxy): pin that reconciliation survives search-tool parse failures

parse_search_tools operates on the dict get_config() already returned and
swallows per-tool errors itself, so a raise from it leaves config_data a
fully valid config with litellm_settings.callbacks untouched. Reconciling
against it is correct.

Deferring config_loaded until after that call looks safer but is not: a
persistently malformed search_tools section would then skip reconciliation
on every poll, so a revoked interception callback would keep serving paid
searches indefinitely. This pins the ordering so it cannot be quietly
reversed.
