GET /ponds/:pondId/links returns the caller's readable slice of the
wikilink graph in one read: nodes (id, title, slug, labelIds for the
coloring), resolved edges deduplicated per direction (a rename can
leave several slugs pointing at one target), and phantom targets with
their referrer ids. An edge survives only when both endpoints are
readable; a phantom disappears entirely once its last readable referrer
is filtered — a hidden page's existence never leaks through any of the
three collections. Trashed pages and their links are excluded.

Shared PondGraphView types feed the knowledge-graph views (#112/#113).
DB tests cover the owner's full graph, the label-DENY reader slice,
edge dedup, trash exclusion, and labelIds on nodes.

Make wikilink relations visible: what links here, and which linked pages
do not exist yet.

- shared: `BacklinkView` gains a plain-text `snippet` for context.
- api: `LinksService` includes a short snippet (from the content cache) with
  each backlink and phantom referrer.
- web:
  - `BacklinksPanel` below a page in read mode: a collapsible "Linked from"
    list (title + snippet, links to the source), hidden when empty. Appears
    on load from the #47 index.
  - `PhantomPagesView` in pond settings: wikilink targets that do not exist
    yet, each with its referrers and a create shortcut that makes the page
    under the phantom slug — resolving those links (#47) and navigating to it.
  - i18n `links` namespace (de + en); backlinks + missing-pages styles.
- e2e `backlinks.spec.ts` (new CI pack): a link created in the editor appears
  as a backlink on the target; the missing-pages view lists a phantom slug and
  creating it navigates to the new page.

Maintain a server-side `page_links` index on every content change so
backlinks and missing-target ("phantom") links can be queried.

- prisma: `PageLink` (from_page_id, nullable to_page_id, target_slug;
  unique per (from, slug); cascade on source purge, set-null on target
  purge); migration.
- shared: `extractWikilinkSlugs(doc)` (distinct target slugs) and the
  `BacklinkView` / `PhantomLinkView` read shapes.
- collab: the persistence hook (#35) now rewrites the source page's outgoing
  links in the same transaction as the content cache — one row per distinct
  wikilink slug, resolved to a page in the same pond (null = phantom).
- api: `GET /pages/:id/backlinks` (permission-filtered — wikilinks resolve
  within a pond, so seeing the pond is the read right) and
  `GET /ponds/:id/phantom-links` (missing targets grouped with their
  referrers). Creating or renaming a page to a slug that pages already link
  to resolves those phantom rows; because links store the target's id,
  backlinks survive a later rename of the target's slug.
- tests: shared extraction unit test; collab persistence db test (store
  writes resolved + phantom rows and rewrites the index); api LinksService
  db test (backlinks, permission filter, phantom aggregation, create/rename
  resolution, id-based backlinks survive target rename).
