Add 15 community knowledge articles from BC Code Intel ingest (#66)
* Add 15 community knowledge articles from BC Code Intel ingest

Ingests net-new /community knowledge from BC Code Intelligence, surviving
the admission test, gray-zone salvage, and dedup against the full corpus.

Domains: ui (6), error-handling (3), performance (2), upgrade (1),
appsource (1), security (1), telemetry (1). The two BC24 No. Series
migration drafts are merged into one article.

Adds good/bad AL samples for the clean-fit articles (error-handling,
performance, security, telemetry). UI and appsource remain knowledge-only.

Validator and knowledge-index checks pass (207 articles).

* Correct SetLoadFields JIT-load article to match MS docs

The draft claimed accessing an unlisted field "reloads the entire row"
per record. Microsoft's partial-records docs say otherwise: the platform
does an implicit Get that loads the missing field(s), and in a direct var
loop the first JIT updates the enumerator so later iterations do not
re-load. The genuine per-row penalty is the pass-by-value case, where the
copy's enumerator is not updated.

Rewrite the article around JIT loading and the by-value footgun, rename
the slug from ...full-reload to ...jit-load, and fix the good/bad samples
to demonstrate the by-value repetition accurately.

# A secret belongs in IsolatedStorage, never in a table field
> Contributions welcome — open a PR to refine or extend this article.
## Description
API keys, OAuth tokens, client secrets, and connection strings must not be stored in an ordinary table `Text` field — not even on a hidden setup table. A regular field is exposed through record reads, page display, RapidStart and Excel export, report datasets, and surfaces in `DataClassification` review; anyone with table permission can read it. The correct home is `IsolatedStorage`, which is invisible to database queries, API pages, and configuration packages. The storage-*location* decision is the rule here; how to scope and encrypt the value once it is in IsolatedStorage is covered separately.
## Best Practice
Persist every credential with `IsolatedStorage`, write it at the point of capture, and read it only when needed. For the per-secret details — choosing the right `DataScope`, encrypting at rest, and typing the value as `SecretText` so it cannot leak into logs — follow `isolatedstorage-datascope-module-vs-company`, `isolatedstorage-setencrypted-for-sensitive-values`, and `secrettext-for-credentials`.
## Anti Pattern
A "Setup" or "Connection" table carrying a `Text` field named `API Key`, `Password`, or `Client Secret`. The value is now readable by any object with table permission, ships in RapidStart packages and Excel exports, and appears in record snapshots — a credential disclosure that no amount of encryption-in-transit elsewhere makes up for. Reviewer signal: a secret-shaped field declared on a table instead of an `IsolatedStorage` call.
