Fix order-filter dropdowns, restructure Konto identity line, drop blog reset link

- CustomSelect.tsx: mousedown on an option blurred the trigger button
  before the click landed, unmounting the list before anything could be
  selected — add preventDefault on the list's mousedown to stop that.
- KontoShell no longer renders "Eingeloggt als ..." above each page's
  content; each page renders its own title then AccountIdentity right
  below it, and ProfileForm's now-duplicate email/Kundennummer line is
  removed.
- Blog category filter: drop the separate "Zurücksetzen" link — clicking
  an active category badge again already deactivates it.
- Werkzeuge cards: more vertical gap between stacked cards below sm:.
- Legal pages' "Stand: ..." line is now derived from the LegalPages doc's
  own updatedAt instead of a hand-typed string.
