Subject: [PATCH] =?UTF-8?q?feat(kontext):=20URL=20import=20helpers=20?=
 =?UTF-8?q?=E2=80=94=20API=20client=20+=20appendContent?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Frontend plumbing for the Kontext "Aus URL" inline panel (the UI
itself was committed earlier as part of 003f75f7e):

- kontext/api.ts: new module-scoped fetch wrapper that talks to
  /api/v1/context/import-url with a Bearer token. Kept in kontext/
  rather than a shared helper because it's the only caller; moving
  it to `context/` would mix two unrelated modules again.
- kontext/stores/kontext.svelte.ts: new appendContent(chunk) method.
  The singleton row is encrypted at rest, so we decrypt the current
  content before concatenating with a '\n\n---\n\n' separator and
  writing back — going through setContent() to keep encryption +
  Dexie hook behaviour consistent.
