fix(config): invalidate model-list TTL cache on default-model change

Browse Source 
set_hermes_default_model() calls reload_config() which resyncs _cfg_mtime,
so the mtime check inside get_available_models() never fires and the POST
response returns the stale cached default. Explicitly drop the TTL cache
after reload so the next read recomputes. Fixes the CI failure in
test_default_model_updates_hermes_config which the prior teardown-only
fix in this PR did not actually address.
