Adds remove(video, options) to the mirror service for delete / toggle-off:
- NIP-09 kind-5 delete referencing BOTH addressable kinds
(34235:pub:root + 34236:pub:root, with k tags) so it's robust to a
since-changed orientation.
- empty-replace tombstone (same d-tag, title, NO imeta) so clients that cache
addressable events but ignore NIP-09 still see the entry cleared; uses the
short kind for portrait videos.
Published to the write/outbox relay set; unavailable without a signer.
tests/nip71-mirror-service.test.mjs: remove publishes delete (both kinds) +
tombstone; portrait => 34236 tombstone; unavailable without signer.
Mutation-verified (tombstone emission + both-kind a-tags load-bearing).
Note: full unit suite green apart from the documented order-dependent flakes
(uploadModal-reset; a transient login-modal clipboard global-state flake) — both
pass in isolation and are unrelated to this change.
