Address Jesper Schulz-Wedde's review on PR #156

- Rename 3 articles so their .good.al/.bad.al companion stems match
  (do-not-change-primary-key, testfield-required-setup-field,
  al-identifiers-english), fixing the R14 orphan-sample errors.
- do-not-change-primary-key.good.al: include Flow in the new table's
  own primary key so it actually models the discriminating dimension.
- al-build-output-must-not-pollute-project-root.md: drop the
  unsubstantiated AL0197 causal claim and the non-existent
  al.outputPath setting; reframe as build-artifact hygiene sourced
  from ALTool --outfolder / al_build outputPath.
- prefer-email-module.md: Email Message is Codeunit 8904, not a table;
  distinguish it from the underlying Sent/Outbox/Draft storage.
- file-datatype-saas.md: File.Open/Create/Read/Write fails to compile
  against a Cloud-scoped project, it does not compile and silently
  fail at runtime.
- namespace-must-be-verified-from-source.md: narrow to "resolve from
  the referenced object's source or symbols," since source-file line
  one is not the only authoritative source (symbol packages, comments
  before the namespace line).
- test-data-must-be-random-and-complete.md: drop "assume an empty
  database" and "collision-free" absolutes; reframe around
  independence from unrelated business records and reserving explicit
  values for scenario-defining inputs.
- binary-choice-must-be-boolean.md: scope to genuine true/false
  semantics, not mechanical two-member-enum-to-boolean conversion.
- document-report-word-layout.md: scope down to a sourced Microsoft
  Learn recommendation instead of an unconditional performance
  guarantee; cite the three Learn pages.
- Wire the new articles into their review skills' candidate-selection
  signals (file-datatype-saas, prefer-email-module,
  namespace-must-be-verified-from-source, var-parameters-require-an-
  addressable-variable) so they can actually enter a worklist.

 ## Description
 
-The classic `File` variable type — `Open`/`Create`/`Read`/`Write`/`Close` against a path on the local or server filesystem — only works on-premises, because there is no accessible filesystem in the SaaS/cloud sandbox. Any extension meant to run in Business Central Online must not rely on `File.Open`, `File.Create`, `File.Read`, or `File.Write` for its core functionality: code built this way compiles but fails, or is silently skipped, in the cloud.
+The classic `File` variable type — `Open`/`Create`/`Read`/`Write`/`Close` against a path on the local or server filesystem — is scoped OnPrem-only. Code targeting Business Central Online that calls `File.Open`, `File.Create`, `File.Read`, or `File.Write` fails to compile against a Cloud-scoped project; it does not compile successfully and fail or get silently skipped at runtime. Separately, and regardless of the compile-time scoping, no server/local filesystem path is available to an extension actually running in Business Central Online.
