Make each admin action self-explanatory and give content appeals a real
effect instead of a dead-end "Dismiss".
- submissionsSection.js: per-type action sets, each button paired with a
one-line description. Applications show Approve (adds to whitelist) / Deny;
appeals that name a real event show "Approve & unblock" (removes the video
from the event block list) / "Keep blocked"; other types show "Mark handled".
- submissionService.js: parse an appeal's `e` tag into targetEventId (trusted
only when it's a well-formed 64-char hex id).
- iframe-content-appeals-form.html: add a required "Blocked video link or
event ID" field; regex-validate + normalize a share link / nevent / note /
hex to the hex event id, tag it as `e`, and include it in the body. Block
submission when no valid reference is provided.
- CSS: stacked action + hint styling; iframe-form .form-hint.
- tests: cover targetEventId parsing (valid, malformed, absent).
