GET /collections/:id/documents accepts filter (field.op.value terms; eq neq
gt gte lt lte like in is; dotted paths index into document data) and order
(field.asc|desc). Whitelisted field/operator parsing with parameterized
values; plain lists keep the sqlc path. CLI gains `documents list
--collection --filter --order`; OpenAPI + generated client updated.
