Add TransactionLog entity and field constants

Introduced the TransactionLog entity for transaction logging. Added FieldNameConstant and DBFieldNameConstant enums for standardized field names, and expanded FieldNameLength with additional constants. Updated SecurityURI and AuthenticationController to support password change endpoint. Fixed PermissionService to use the correct repository for user permission updates.
