Fix account-nav feedback, blog filter position, and small icon polish

- Remove Merkliste from AccountNav — the Navbar's own wishlist icon already covers it, a second nav entry was redundant.
- Fix duplicate "Mein Profil" heading (ProfileForm already renders its own; KontoShell no longer adds a second one).
- "Eingeloggt als ..." now renders once in KontoShell, consistently on every /konto/* page, instead of only on the orders page.
- Blog category filter chips moved into the hero's own text column (was a separate bar below the entire hero including the photo) — visible immediately on every width instead of requiring a scroll past the hero image first.
- ArrowRightIcon's arrowhead wings shortened (looked like a generic oversized chevron at full length).
- Search overlay's "Esc" text button replaced with an X icon; the actual Escape keyboard shortcut is unchanged.
