Financial Setup Has Independent Permissions and Versioning

Context

The milestone preserves separate authority for catalogue editing and financial treatment. Roles can therefore receive setup access independently.

Decision

A product's optional accounting setup has independent permissions, version and protection and is maintained through its own operations.

Alternatives Considered

Include finance fields in every catalogue write. A shared permission boundary would bind ordinary product changes to financial authority.

Consequences

The current page lacks an accounting-only edit mode. A combined request for callers holding both permissions remains a product option rather than a requirement inferred from the permission split.
