AL methods limited during write transactions (RunModal, Codeunit.Run) (#161)
* Add runmodal-is-not-allowed-inside-write-transactions.md; drop "modal page" from the prompts article

A modal page does not behave like Confirm/StrMenu inside a write
transaction: the platform refuses Page.RunModal (and Report/XmlPort
.RunModal with a request page, and Codeunit.Run with its return value
used) with a runtime error instead of holding the lock. The new article
documents that guard - verified against Microsoft Learn (Codeunit.Run
transaction semantics), microsoft/AL#5452, Microsoft's own Base
Application (Commit(); Page.RunModal pattern), and a live reproduction
on Business Central 26 quoted verbatim. avoid-user-prompts-inside-
transactions.md keeps its scope to the prompts the platform does allow;
"modal page" is removed from its list because that case is refused, not
stalled.

* Do not list Message among the lock-holding prompts

Message runs asynchronously - it is queued and shown when the calling
method ends or another method requests input - so it never pauses the
transaction and holds no lock. Only Confirm and StrMenu wait for the
user.

* State the four write-transaction conditions as one explicit line per method

Mirrors the structure of the platform's own error message so the
Report.RunModal and XmlPort.RunModal request-page exceptions are
visible at a glance instead of buried in prose.

* Title the article after the platform error it explains

"AL methods limited during write transactions: commit before RunModal
and Codeunit.Run" - so a developer or agent searching for the runtime
error text lands on the one article that covers all four restricted
methods. Slug and sample stems renamed to match; keywords gain the
error's own phrase and the legacy Form.RunModal name it still uses.

* Trim keywords to 10 per validator guidance

* Wire the new article into al-performance-review.md

Adds Page.RunModal / Report.RunModal / XmlPort.RunModal / UseRequestPage
to the extracted-token list and one deterministic worklist cue with
exclusions, so the article is selected from the RunModal call itself
rather than only via a co-located Commit/Modify token. Codeunit.Run in
that position is routed to its existing owner article.

* Correct XmlPort.RunModal to Xmlport.Run; fix READ-convention sample links

XmlPort has no RunModal method (static or instance) - Microsoft Learn
confirms only Xmlport.Run(Integer [, Boolean RequestWindow] [, Boolean]
[, var Record]). Replaces the invented API with the real one throughout
the article, worklist cue, and token list, and explains the platform
error message's own "XmlPort.RunModal" wording as the same kind of
legacy phrasing already noted for Form.RunModal/RequestForm.

Also corrects UseRequestPage(false): that's a Report instance method
only, not applicable to XMLport, which uses the UseRequestPage = false
object property or Run's RequestWindow argument instead.

Fixes the two sample references to use the READ-convention markdown
link form (Test-KnowledgeIndex.ps1's Knowledge-Retrieval.ps1 check was
failing on plain backtick text).

Rebased onto upstream/main to resolve conflicts with #148's job-queue
additions to al-performance-review.md - both sets of worklist tokens
and cues are retained.

* Add Report.Run alongside Report.RunModal to the write-transaction guard routing

al-performance-review.md's tokens/cues only recognized Report.RunModal,
so a failing Modify(); Report.Run(..., true, ...) path was never
worklisted even though Report.Run shares the exact same RequestWindow-
blocking-dialog mechanism as Report.RunModal (they differ only in
whether the report instance is cleared afterward). Added Report.Run to
the token list and the targeted cue, with the same request-page-
suppressed exclusion, and extended the knowledge article's Description
bullet to name both methods explicitly instead of only RunModal.
