Editor heart piece: first filled-canvas pattern (block cards + edges)

Built the missing core of the flow editor as a new Subframe page "S01d
Editor gefuellt": a filled canvas with a real left-to-right flow —
Neue Anfrage -> Wenn-Dann -> (Ja) Aufgabe anlegen / (Nein) E-Mail senden.

Validated with Dejan (2026-07-17):
- Flow direction: left to right (n8n pattern)
- Card content: icon + name + plain-text summary (e.g. "Neue Anfrage —
  aus Quelle: Website"), so the whole flow reads without opening cards
- Category colour on the icon; branch cards (Wenn-Dann) get two right
  connection points, green "Ja" over neutral "Nein"

Editor chrome (header, mode toggle, minimap, toolbar) matches V1
Vollbild minimal. Obsidian synced: new screen file S01d, tracker row
updated from "FEHLT" to "In Subframe", canvas node now points to the
built page.

Still to build (noted in S01d): selected-card state, inline validation
badges (not connected / missing field / loop), empty->filled transition,
right-click node menu, real edge interaction.
