`accountants.access.update`

Extend, shorten or clear an accountant's access end date and, optionally, change their access level to read, comment or prepare (exactly that preset, nothing more), with userId, expiresOn (YYYY-MM-DD or null) and/or preset, expectedRevision and idempotencyKey. Extra permissions never outlast the end date. Administrator access is required. MCP calls also require accounting:admin; the web agent asks for approval before changing outside access. Direct API requests cannot perform these access-granting actions.
