* Fix bank config API for multi-tenant schema isolation
- Use fq_table() in config_resolver.py to schema-qualify bank table queries
- Add authenticate_and_resolve_schema() to bank config API handlers in http.py
Without these fixes, bank config operations in multi-tenant mode hit
public.banks instead of tenant_xxx.banks, causing "column config does
not exist" errors.
* Fix method name: _authenticate_tenant not authenticate_and_resolve_schema
The MemoryEngine method is _authenticate_tenant(), not
authenticate_and_resolve_schema(). This was causing AttributeError
on all bank config API requests.
