fix(meta-compile,meta-validate): fix 7 e2e bugs, add hints and reserved name checks

Group 1: ExchangePlan — remove invalid CodeType/CheckUnique/Autonumbering;
Flowchart.xml — add version="2.17"; Content.xml — fix namespace + version.

Group 2: Add missing GeneratedType categories — DefinedType, ChartOfAccounts
ExtDimensionTypes/Row, CalculationRegister RecalculationsManager/Recalcs.

Group 3: BusinessProcess — emit <Task> property from DSL.

Group 4: Cross-reference [HINT] output after compilation for AccountingRegister,
CalculationRegister, BusinessProcess, ChartOfAccounts (oriented to /meta-edit DSL).

Group 5: Reserved attribute name warnings in meta-compile and meta-validate
(Check 7b); cross-reference validation in Check 10 with [HINT] output.

All changes synced to both PS1 and PY versions.
