feat(fof-layer1): Tauri commands + frontend UI for vouches

Browse source 
Node helpers (crates/core/src/node.rs):
- vouch_for_peer(target): derives target X25519 pub from NodeId,
  inserts into own_vouch_targets, republishes bio post so the new
  VouchGrantBatch propagates to the receiver via CDN.
- revoke_vouch_and_rotate(target): per Scott's design, revocation IS
  the rotation primitive. Marks target current=0, generates new V_me
  epoch in vouch_keys_own (prior retained, Layer 4 receiver-chain),
  republishes bio. Revoked persona retains old V_me → grandfathered
  access to old content; locked out of new content sealed under V_new.
- list_vouches_given / list_vouches_received: enriched with display
  names via resolve_display_name.

Tauri commands (crates/tauri-app/src/lib.rs):
- vouch_for_peer, revoke_vouch_for_peer (single-action commands)
- list_vouches_given, list_vouches_received (DTOs with camelCase)
- All registered in the generate_handler! list.

Frontend (frontend/index.html + app.js):
- New "Vouches" section in Settings tab with side-by-side Given /
  Received lists. Per-row Revoke button on Given entries with confirm
  prompt explaining the rotation semantics.
- Bio modal gains Vouch / Revoke Vouch button next to Follow/Unfollow.
  State derived from list_vouches_given on modal open.
- loadVouches wired into the settings-tab activation handler.
