fix: auth, wallet linking, Luca chat, and stablecoin USD pricing

[danbuildss]

Summary

• Auth fix for Gmail/X users: privy:<id> strings were being written to access_codes (UUID primary key) — silently failing for all Privy-authenticated users. Added routing to the users table (text PK) in /api/access and /api/user/wallet.
• Unlink wallet: DELETE handler was missing from /api/user/wallet — added it.
• Luca chat gate removed: Chat was blocked unless a wallet was linked. Gate removed — anyone can chat.
• Hermes integration: Dashboard chat now proxies to @AskLucaBot via the Hermes API (HERMES_API_URL + HERMES_API_KEY env vars). Consistent with the Telegram bot.
• Telegram link fix: All bot links corrected to @AskLucaBot (not the community group @asklucaai).
• Stablecoin USD pricing: Both Alchemy and Etherscan chain providers had valueUsd: undefined hardcoded. Added usd-pricer.ts that prices USDC/USDT/DAI across Base/Ethereum/Arbitrum/Optimism/Polygon deterministically (1:1 peg, raw value ÷ 10^decimals). Fixes financial intelligence snapshots always returning $0.

Before merging

Run this in Supabase SQL editor if the users table doesn't exist yet:

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;

(Skip the policy line if it already exists.)

After merging

Re-index Skopos wallets then re-run the financial intelligence process endpoint to get real USD metrics from stablecoin transactions.
