J.C. Bartle bf251b820f ♻️ refactor: Pass OBO upstream-token closure into MCP instead of req
Build the OpenID upstream-token provider at the request boundary and thread
only the closure through MCP handling, so the MCP service layer no longer
receives the raw Express request. The closure still reads/refreshes the live
session at tool-call time, preserving the walk-away recovery.

- Drop `req`/`capturedReq` from createMCPTools, createMCPTool, reconnectServer,
  createToolInstance, and reinitMCPServer; forward `upstreamTokenProvider`
  instead. Closure is constructed in loadTools, loadToolDefinitionsWrapper, and
  the reinitialize route, where req/res are in scope.
- OBO: fall back to user.federatedTokens when the provider yields no live
  session, so OIDC remote-agent calls (verified bearer, no session) still work.
- Inline refresh: mirror a rotated refresh token to the refreshToken cookie via
  a shared setRefreshTokenCookie helper, guarded by !res.headersSent (no-op on
  the streaming path; session copy stays authoritative).
- Single-flight: hydrate a joining request's own session from the resolved
  tokens so a later OBO call doesn't replay a rotated-away refresh token.

Addresses owner feedback and three review findings.
