Add "Always show creator" overlay button for account-level WoT override

Adds a second entry point (alongside the Safety-tab npub input) for the
per-author moderation override. On blurred/warned video surfaces, an
"Always show creator" button now sits beside "Show anyway". Clicking it
dispatches a `video:trust-author` document CustomEvent; the single app-level
listener in applicationBootstrap.js applies the account-level override and
refreshes affected videos, clearing the web-of-trust warning for every video
from that creator until reset.

Wired into VideoCard, VideoModal (persistent reused button + teardown
cleanup), and SimilarContentCard.
