builtbykev 1c681df5d3 DS1 (design): speed + trust bugs
Fixes the three DESIGN-SPEC Part 4 + #17 audit findings.

1. React #418 hydration mismatch (landing → dashboard entry). The
   `maybeSignedIn` value was computed in a useState INITIALIZER that reads
   localStorage during render: server (no window) → false → emits the
   marketing tree; a signed-in visitor's first CLIENT render → true → emits
   the loading placeholder. Whole-subtree server/client mismatch → React
   discarded and re-rendered the page. Deferred behind a mounted flag so the
   first client render matches the server; the stored-session check flips
   post-mount. SSR HTML is no longer discarded.

2. Loading walls → skeletons. New tokenized Skeleton primitive
   (.vyndr-skeleton, reduced-motion-safe via the global rule). Swapped into
   every text-wall loader: dashboard slate load ("Loading the slate…"), /desk
   ("Assembling the pack…"), /ledger ("Loading…"), scan ("Loading the model…"),
   and the landing redirect placeholder. No bare text loader remains.

3. scan→ledger persistence. Root cause: the scan page read its bearer token
   from localStorage['sb-token'] — a key written ONLY by the OAuth callback —
   so email/password users posted /api/scan anonymously and the ledger write
   (gated on an authed user) was silently skipped. Now uses the authoritative
   session.access_token (matching the ledger read path). Extracted the row
   builder to web/src/lib/ledgerRow.js (shared, testable).

Tests: +17 (scanLedgerPersistence write→mine round-trip + scope + idempotency;
ds1SpeedTrust hydration/skeleton/persistence source invariants). Full suite
233 suites / 2793 green; web build exit 0.
