feat(settings): open Assistenten on Kunskap with the konteringskarta first (#1044)

The Assistenten settings hub used to open on Minne, with the
konteringskarta buried two clicks away (Kunskap tab, below a second
nested tab row). Now /settings/assistant opens on Kunskap and the
LedgerGraph hero is the first thing on screen.

- Kunskap is the default view and first tab; Minne moves to ?view=memory
  (old ?view=knowledge links still resolve to the default)
- Drop the nested Kompetens/Minne/Regler & profil tab row inside the
  Kunskap view: Kompetens and Minne duplicated the top-level tabs one
  row above; Regler & profil now renders inline under the graph with a
  section header (KnowledgeTabs.tsx deleted)
- Restore vertical rhythm (space-y-8) between the hero, detail section
  and footer, lost when the view moved into the settings tabs
- Update redirects and memory deep links (/settings/agent-memory,
  AgentChat memory chips, FactsCard manage link) to ?view=memory
- Match the loading skeleton to the new layout
