Add source-verified Finance knowledge and review domain (#57)

* Add Finance posting domain-knowledge pilot

Adds three atomic domain-rule knowledge files under community/knowledge/finance/ as a pilot for Type-A (normative) Business Central domain knowledge: post through the posting engine, treat posted ledger entries as immutable, and treat the Dimension Set ID as the source of truth for dimensions. Includes a good/bad AL sample pair for the posting rule.

These encode BC-specific invariants that LLMs reliably get wrong, fitting the existing remedial/atomic knowledge grain with no schema or contract changes. Passes the repo frontmatter validator and is discovered by the knowledge index.

* Clarify editable operational fields on posted ledger entries

Addresses review feedback from @JeremyVyska on PR #57: the immutability rule applies to financial content, not the whole entry. Reframes the Description around financial content and gives the operational-field exception (payment/application data, on-hold, applies-to, communication fields edited via CustEntry-Edit/VendEntry-Edit and the ledger entry pages) its own paragraph in Best Practice instead of understating it as a narrow set.

* Expand Finance pilot into a source-verified review domain

Move Finance knowledge to the Microsoft-owned layer, add nine scoped rules with eighteen AL samples, and register bounded Finance review with complete paired evaluation coverage.

* Fix Finance review applicability and ownership boundaries

Remove application-area gating and later VAT-field dependencies, align dynamic shared conventions, separate SCM ownership, and keep journal examples focused on the intended invariant.

+# Apply and unapply entries through the application workflow, not status flags
+
+## Description
+
+Customer/vendor settlement is a posting operation involving detailed ledger entries, not just a change to `Open` on the main entry. Remaining amounts are calculated from detailed entries. Unapplication posts correcting entries and handles application-derived effects such as discounts and currency gains/losses; deleting details or changing `Unapplied` cannot reproduce that history.
+
+## Best Practice
+
+Use `"CustEntry-Apply Posted Entries"` / `"VendEntry-Apply Posted Entries"` and the supported application or unapplication workflow. Let it check application dates, entry state, and application ordering. The `ApplyCustEntryFormEntry` / `ApplyVendEntryFormEntry` and `UnApply...LedgEntry` methods are **interactive**: users select and confirm the operation. They are not unattended "mark paid" APIs.
+
+For programmatic posting, use the target version's public `Apply` / `PostUnApply...` APIs with properly prepared selection and `Apply Unapply Parameters`; handle cancellation and the workflow's transaction/commit behavior. `"Applying Entry"`, `"Applies-to ID"`, and `"Amount to Apply"` are legitimate application-preparation fields. Do not report their writes alone, temporary buffers, supported posting/compression internals, or unrelated operational/extension fields.
+
+See sample: [`apply-ledger-entries-through-application-codeunits.good.al`](apply-ledger-entries-through-application-codeunits.good.al).
+
+## Anti Pattern
+
+Implement customer/vendor payment matching, settlement, or reopening by directly persisting `Open`, `"Closed by Entry No."`, closure amounts/dates, or detailed-entry unapplication flags, or by deleting/rewriting detailed application amounts. Require confirmed writes to existing non-temporary customer/vendor or detailed customer/vendor entries and settlement intent. Item/inventory application records belong to SCM, not this rule. Do not suggest assigning a `Remaining Amount` FlowField as a fix.
+
+This article owns fabricated application state. Use the [posted-financial-content rule](do-not-modify-or-delete-posted-ledger-entries.md) for original accounting-value corrections, not a second finding prescribing the same application fix.
+
+See sample: [`apply-ledger-entries-through-application-codeunits.bad.al`](apply-ledger-entries-through-application-codeunits.bad.al).
