feat: Stockbit login for the order book, live quotes and daily history

Opt-in, with the user's own Stockbit session from a pasted
credentialStorage cookie (or IDX_STOCKBIT_REFRESH_TOKEN):

- idx stockbit login/status/logout; session file 0600, tokens never shown
- rotating refresh under a cross-process lock; one refresh+retry on 401
- stocks orderbook: depth with lots and orders, OHLC, value, foreign flow
- --provider stockbit quotes from the session API when logged in
- --history-provider stockbit, and auto under the stockbit provider for
  5d-1y daily windows
- MCP get_orderbook and stockbit_status (17 tools)
