The Memory & Context tab dropped any section key missing from
/api/config/schema, so when the backend began skipping memory.provider
(hidden in favor of the web dashboard's Plugins page) the desktop lost
its Memory Provider picker entirely, along with the provider config
panel and OAuth connect affordance mounted under it.
The desktop already declares its form in constants (section keys,
labels, enum options), and GET /api/config still returns the value.
Gate row existence on config presence instead: use the schema entry
when present, otherwise infer the field type from the config value.
Keys unknown to an older backend stay hidden since they are absent
from its config too.
