fix(schema): derive rawConfigSchemaDeepPartial from rawConfigSchema

Address Copilot review feedback by deriving rawConfigSchemaDeepPartial
from rawConfigSchema using .extend() instead of duplicating fields.
This fixes the missing rtl field and prevents future drift between
the two schemas.

- Add test case for rtl field acceptance
- Remove misleading comment about config source
