Adds forgot/reset password flow with dev-mode email logging, multiple
named/revocable API keys per user (replacing the single legacy key model
while keeping it working), per-tool-call usage analytics recorded from the
MCP call_tool handler, and a separate admin API (auth/queries/routes) for
managing all users and viewing system-wide analytics — authenticated via a
hardcoded operator identity, fully isolated from regular user auth.

Replaces the old SseServerTransport (broken against current MCP clients —
405s on POST, session-id redirects, no protocol negotiation) with
StreamableHTTPServerTransport. Adds an idle-session sweeper to prevent
abandoned client connections from leaking memory indefinitely, CORS
middleware for browser-based frontend access, and PUBLIC_URL/CORS_ORIGINS
settings so signup responses show the correct connection URL instead of a
placeholder.
