fix: Gmail/X sign-in auth + wallet linking + Luca chat gate

[danbuildss]

Summary

• Users table — new migration creates public.users keyed by privy:<privyId> for all Gmail/X sign-in accounts. Previously Privy users had no persistent row anywhere, so wallet saves silently failed.
• Wallet API fixed for Privy users — GET/POST/DELETE /api/user/wallet now routes Privy users to the users table and access-code users to access_codes. Linking and unlinking both work correctly.
• Unlink button fixed — added the missing DELETE handler (Settings page was calling it but it didn't exist).
• Luca chat gate removed — chat is open to anyone logged in. Wallet linking is optional — it just auto-selects your agent in the dropdown.

Before merging — run this in Supabase SQL editor

CREATE TABLE IF NOT EXISTS public.users (
  id           text PRIMARY KEY,
  email        text,
  x_handle     text,
  wallet       text,
  last_seen_at timestamptz DEFAULT now(),
  created_at   timestamptz NOT NULL DEFAULT now()
);
ALTER TABLE public.users ENABLE ROW LEVEL SECURITY;
CREATE POLICY "Service role can manage users" ON public.users FOR ALL USING (true) WITH CHECK (true);

Test plan

• Sign in with Gmail → wallet link in Settings saves and reads back correctly
• Sign in with X → same
• Unlink wallet button works (no 404)
• Luca chat opens immediately without needing a wallet linked
• Link wallet matching an agent → agent auto-appears in chat dropdown
