- Add m_client.signature_id (single-slot pointer, mirrors image_id) plus ClientSignatureIdAdapter/EntitySignatureIdAdapter so re-uploading a signature updates the existing m_document row in place instead of leaving duplicate rows behind that readers picked inconsistently. - Fix CkycBatchBuilderServiceImpl address-proof classification to read the client identifier's actual m_code (KYCAddressProofType vs KYCIdProofType) instead of a hardcoded string set that disagreed with the CKYC tab and silently dropped Aadhaar-as-address-proof identifiers. - Organize the CKYC ZIP into per-artefact-type folders (PHOTO/SIGNATURE/ID_PROOF/ADDRESS_PROOF). - Fix CkycBatchBuilderServiceImpl.createBatch() using the daily batch sequence number as the ZIP document's parent_entity_id instead of the real m_ckyc_batch.id, which 404'd on download whenever the two diverged (i.e. almost always). - Add monthlyTurnover and annualIncome fields alongside the existing annualTurnover/monthlyIncome. - Add isSeniorCitizen, isPwd, and pwdCategory (proper m_code_value-backed PwdCategory code, not a free-text column) to m_client, following the same pattern as occupation/religion/marital status. - Add Diploma as its own Education Level (with diploma-specific DegreeQualification values) and Graduate as a level distinct from Undergraduate.
