fix: Consolidate OAuth callbacks and implement PKCE for all flows
This PR fixes multiple OAuth-related issues: ## Unified OAuth Callback - Consolidated `/oauth/callback-nextcloud` and `/oauth/login-callback` into single `/oauth/callback` endpoint - Flow type determined by session lookup via state parameter (no query params in redirect_uri) - Fixes redirect_uri validation issues with IdPs requiring exact match - Legacy endpoints kept as aliases for backwards compatibility ## PKCE Implementation - Implemented PKCE (RFC 7636) for Flow 2 (resource provisioning) - Generate code_verifier and code_challenge - Store code_verifier in session storage - Retrieve and use in token exchange - Fixed PKCE for browser login (integrated mode) - Previously only worked for external IdP (Keycloak) - Now works for both Nextcloud OIDC and external IdP ## Login Elicitation Fixes (ADR-006) - Fixed elicitation URL to route through MCP server endpoint - Changed from direct Nextcloud URL to `/oauth/authorize-nextcloud` - Ensures PKCE is properly handled by server - Fixed login detection after OAuth flow completes - Look up refresh token by state parameter instead of user_id - Works even when Flow 1 token not present - Added `get_refresh_token_by_provisioning_client_id()` method ## Session Authentication - Fixed `/user/page` redirect loop - Shared oauth_context with mounted browser_app - SessionAuthBackend can now validate sessions correctly ## Tests - Added comprehensive login elicitation test suite - Updated scope authorization test expectations - All 43 OAuth tests passing ## Files Changed - `app.py`: Shared oauth_context, unified callback route - `oauth_routes.py`: Unified callback, PKCE for Flow 2 - `browser_oauth_routes.py`: PKCE for integrated mode - `oauth_tools.py`: Fixed elicitation URL generation - `refresh_token_storage.py`: Added lookup by provisioning_client_id - `test_login_elicitation.py`: New test suite 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
