Approving a content appeal now checks WHY the video is hidden and applies
the right fix, instead of only ever touching the per-event block list.
- submissionFacade.js: resolveEventAuthorHex({ eventId }) looks up the event
and returns its author hex — the authoritative author, so we don't rely on
the appellant to supply it.
- submissionsSection.js approveAppeal: branch on the real block state.
* Author-level block (whole npub) → its own strongly-worded confirmation
("restores ALL their content"); on confirm, removeFromBlacklist plus any
event block. Never bundled into the default unblock.
* Event-level block only → unblock this video (as before).
* Neither → distinguish "nothing to unblock" from "couldn't verify on
relays" and just mark the appeal resolved.
- tests: resolveEventAuthorHex (author normalization, blank/not-found).
