feat(activities): tailor Hosting tab + host detail view for operators

Hosting feed (ActivitiesPage when onlyHosting):
- Hide the date picker strip + calendar shortcut and the entire
  Filters/temporal-pills row; an operator managing their roster
  doesn't need calendar navigation or temporal narrowing.
- Keep the search bar — finding a specific event in a long roster
  still matters.
- Render compact cards via a new `compact` prop on ActivityList +
  ActivityCard: no hero image, single-line title, no summary, no
  bookmark, no "Yours" badge (every card is the operator's own),
  tighter p-3 padding, single-column flex layout.

Host detail view (ActivityDetailPage when ownedLnbitsEvent):
- Drop the top-bar Scan and Edit buttons. Edit moves into the title
  row as a prominent filled-primary icon button right of the title;
  Scan moves into the tickets section.
- Render a full-width "Scan tickets" CTA in place of Buy ticket, and
  hoist it outside the ticketInfo gate so it appears even on hosted
  events that were published without AIO ticket tags.
- Hide BookmarkButton and RSVPButton for the host (favoriting /
  RSVPing your own event are noise affordances).

Detail-page badge row: "Yours" leads the row in the highlighted
secondary variant; category and tags drop to outline so the
ownership signal stands out.
