* SpeakerSelfNominatePanel — Story 7.2 "I Could Speak on That".
*
* An "I could speak on that" button on an upcoming-event card. Visible only to logged-in users
* (the caller also gates on topic-set + published). Clicking opens a small form (title + abstract)
* that self-nominates the attendee as a speaker FOR THAT event — the card supplies the eventCode,
* so no event picker is needed and multiple simultaneous open events each get their own button.
*
* Tailwind-only by design: the upcoming-event card lives on the public (no-MUI) homepage. The form
* lives in a Radix Dialog (rendered in a portal) so its clicks don't bubble to the card's <Link>;
* the trigger button stops propagation + prevents default for the same reason.
*
* Identity (name + company) is auto-filled server-side from the attendee's profile — the body
* carries only the proposed talk. One self-nomination per attendee per event (the backend rejects
* a repeat with 409 `DUPLICATE_SELF_NOMINATION`); we render the already-done state on success or on
* that duplicate error. The backend reuses 409 for a second condition — `SELF_NOMINATION_NOT_ALLOWED`
* (topic unset / event unpublished, e.g. a race after the card rendered) — so we key on
* `details.code`, NOT the bare status, and surface the generic error for the not-allowed case.
