fix(events): collapse own-event draft + relay copy into one card

Coordinate-keying the events store (kind:pubkey:d-tag) regressed the
own-events merge: a creator's own event showed up twice in the feed.

`loadOwnEvents` surfaces the caller's own LNbits events via REST
(`ticketedEventToEvent`) so drafts appear before their NIP-52 event is
on a relay. That adapter stamps an empty `organizer.pubkey`, `isMine`,
and no ticket info. The relay-published copy lands under the real
publisher pubkey (`resolve_for_wallet` — NOT the user's Nostr login
key) with full ticket counts. Pre-coordinate-keying both collapsed on
the bare d-tag so the relay copy replaced the draft; under
`kind:pubkey:d-tag` the empty-pubkey draft and the real-pubkey copy are
distinct keys, so both render — the empty "..."/no-tickets card next to
the real one. Only the logged-in owner sees it, since only own events
get the REST merge.

upsertEvent now reconciles by d-tag: the published copy supersedes the
provisional draft and inherits its `isMine`, so the creator keeps the
Yours badge + Hosting filter even though the publisher key differs from
their login key. Handles both arrival orderings; a draft with no
published copy yet (pending review) still shows alone; genuinely
distinct authors sharing a d-tag are untouched.
