Users in Docker mode had to re-login every ~1 hour when the access token expired. This adds a refresh token mechanism (7-day JWT) so the frontend can silently obtain new access tokens without requiring re-login. Backend changes: - Add refresh_token field to Token response model - Issue refresh tokens alongside access tokens on Docker login - Add POST /auth/refresh endpoint for token rotation - Add type claim to JWTs to distinguish access vs refresh tokens - Reject refresh tokens used as Bearer tokens for API auth - Fix ACCESS_TOKEN_EXPIRE_MINUTES import (was 60 in jwt.py, 120 in settings.py) Frontend changes: - Store refresh token in localStorage on login - Attempt silent refresh on 401 before redirecting to login page - Proactively refresh access tokens expiring within 5 minutes - Clear refresh tokens on logout https://claude.ai/code/session_018c9637emA3RsjJhg9aLUz6

Summary
Implements refresh token functionality to enable long-lived sessions in Docker mode while maintaining security through short-lived access tokens. This allows users to remain logged in without re-entering credentials when their access token expires.
Key Changes
Backend (flowfile_core):
create_refresh_token()anddecode_refresh_token()functions to handle refresh token generation and validation/auth/refreshendpoint that exchanges a valid refresh token for new access and refresh tokensACCESS_TOKEN_EXPIRE_MINUTESto settings and addedREFRESH_TOKEN_EXPIRE_DAYSconstant (7 days)Frontend (flowfile_frontend):
AuthResponseinterface to include optionalrefresh_tokenfieldrefreshAccessToken()method to exchange refresh tokens for new access tokensImplementation Details
