feat: "Email sent" column and per-event copy-to-organizer BCC (1.6.1-aio.15)

Organizers had no way to see whether a ticket email went out short of
reading the Postfix journal, and no copy of what the attendee received —
LNbits submits over SMTP, so nothing lands in a Sent folder.

- Admin ticket table gains an "Email sent" column derived from
  `extra.email_notification_sent` ("✓ sent" / "not sent" / "unpaid" /
  "no email").
- `extra.copy_to_organizer`: BCC every ticket email to the event's
  reply-to address (explicit, else the owner's account email) on the SMTP
  envelope only — no Bcc/To header, and skipped when the buyer *is* that
  address. Toggle sits with the other delivery switches in the admin form.
