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.

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.
