feat(ui): event autocomplete + log-bet deep link, steam-move label

- MyBets: add a "Find event" MudAutocomplete over upcoming events (loaded once,
  filtered client-side) that fills the Event ID; the manual ID field stays as a
  fallback. Backed by IBetJournalService.GetUpcomingEventOptionsAsync.
- Add a "Log bet" CTA on the anomaly detail page that deep-links to
  /my-bets?eventId=<code>; the journal prefills the Event ID from the query.
- Render the new SteamMove anomaly kind with a localized label in the card and
  detail KindLabel switches (was falling through to the raw enum name).
- Localization (en+ru) for all new strings.
