fix(meta-compile): fix String/Number length loss, RegisterRecords format, CommonModule prefix

- Parse-AttributeShorthand: combine type + length/precision from separate
  JSON fields (String→String(N), Number→Number(D,F)) — fixes SDBL error
  "Строка без спецификации длины недопустима"
- Constant valueType: same length combination fix
- DefinedType: accept both valueType (singular) and valueTypes (plural)
- ChartOfCharacteristicTypes: default String length 0→100
- Document RegisterRecords: <xr:Record> → <xr:Item xsi:type="xr:MDObjectRef">
- ScheduledJob.MethodName, EventSubscription.Handler: auto-prepend CommonModule. prefix
- meta-validate check 13: support 3-part method format (CommonModule.Module.Proc)

E2E verified: 18 types (21 objects) pass cf-init → meta-compile → LoadConfigFromFiles → UpdateDBCfg
