// components/ShareholderChangeTable.tsx
//
// Section 5 — "Change in shareholders": the list of shareholder-change
// resolutions and the actions available on each.
//
// WORKFLOW THIS ENCODES
// ---------------------
//   1. Operator fills in the wizard  → draft resolution is created, nothing sent
//   2. [⋯] Preview letter             → renders a fresh PDF in a new tab
//   3. [⋯] Email to all parties       → renders, files and emails that PDF;
//                                        parties print, sign by hand, return it
//   4. [⋯] Upload document            → choose the slot FIRST: the signed
//                                        resolution, or the signed share
//                                        certificates, which are made outside
//                                        the app and come back separately
//   5. [⋯] Mark as complete           → status closes the loop
//
// This mirrors section 4 exactly: every action lives in the row's kebab, not as
// inline buttons, so the row stays readable and there is one target to hit.
// Creating a draft sends nothing — mailing is always a separate, explicit click.
//
// Steps 4 and 5 are separate on purpose. Section 5 has no browser signing flow,
// so the signed copy arrives out of band and the operator files it; being able
// to fix a status without re-uploading a file is the point.
//
// A note on sending: the API returns 200 once it has PROCESSED the send.
// Per-recipient delivery is in the response body (`emailed[].ok`, `skipped`) and
// this component renders that result rather than assuming success — a green tick
// that is not backed by a real send is worse than a visible failure.
//
// DELIBERATE NON-SHARING: `ResolutionsTable.tsx` (section 4) has a very similar
// portalled kebab. It is duplicated rather than extracted because section 4's
// component is frozen — refactoring it risks changing the legal output and the
// section-4 flow that is already in daily use.
//
// The upload destination picker below is kept deliberately equivalent to
// section 4's so an operator moving between the two tabs finds the same menu.
// The one difference is the slot list: section 5 has TWO slots on the resolution
// itself (signed resolution, signed share certificates), where section 4 has
// one on the resolution plus one per director.
