feat(inbound-api): surface method compile errors to operators — api-method validate/recompile + compile state on get (ScadaBridge#75)

The data plane answers a broken inbound method with the generic "Script
compilation failed for this method"; the Roslyn diagnostic reached only the
central log, and the known-bad cache could not be observed or reset per method.

- InboundScriptExecutor keeps the diagnostics with each known-bad record and
  exposes GetCompileState(name, currentScript): IsCompiled / IsKnownBad /
  LastCompileError, judged against the current script text (a record for older
  text is reported as not compiled yet).
- Management: ValidateApiMethodCommand (compile the stored script, return
  ApiMethodCompileResult, register nothing, cache untouched) and
  RecompileApiMethodCommand (CompileAndRegister without re-sending the entity,
  drops the node's ApiMethodCache row, audited "Recompile"). Both Designer, like
  UpdateApiMethod; dispatched through the shared ApiMethodCompileOperations.
  GetApiMethod keeps the entity fields top-level and adds isCompiled,
  isKnownBad, lastCompileError and compileStateNode. Compile state is per
  central node and every result names the node.
- CLI: api-method validate --id, api-method recompile --id.
- Central UI: the API-method edit page shows the saved script's compile state
  and last error, with Validate and Recompile actions (same operations, same
  Designer gate, fresh DI scope).
- RequiredRoleMatrixTests entries; ManagementSurfaceParityTests covers the new
  CLI leaves; ApiMethodCompileDiagnosticsTests + an executor CompileState test.
- Docs: CLI README, Component-CLI/ManagementService/InboundAPI, components/*.
