Chris Coutinho 2a1274d8a8 refactor: Unify OAuth configuration to be provider-agnostic
Replace provider-specific environment variables (OAUTH_PROVIDER, KEYCLOAK_*)
with generic OIDC_* variables that work with any OIDC-compliant provider.

**Key Changes:**
- Auto-detect provider mode from OIDC_DISCOVERY_URL issuer
  - External IdP mode: issuer ≠ NEXTCLOUD_HOST (Keycloak, Auth0, Okta, etc.)
  - Integrated mode: issuer = NEXTCLOUD_HOST (Nextcloud OIDC app)
- Unified OIDC discovery flow (single code path)
- Generic client credential loading (static or DCR)
- Simplified docker-compose.yml environment variables

**Environment Variables:**
BEFORE:
  OAUTH_PROVIDER=keycloak
  KEYCLOAK_URL=http://keycloak:8080
  KEYCLOAK_REALM=nextcloud-mcp
  KEYCLOAK_CLIENT_ID=...
  KEYCLOAK_DISCOVERY_URL=...

AFTER:
  OIDC_DISCOVERY_URL=http://keycloak:8080/realms/nextcloud-mcp/.well-known/...
  OIDC_CLIENT_ID=nextcloud-mcp-server
  OIDC_CLIENT_SECRET=...

**Benefits:**
- Works with any OIDC provider without code changes
- No manual provider selection needed
- Cleaner environment variable naming
- Reduced code duplication (~150 lines removed)

**Testing:**
 mcp-keycloak auto-detects external IdP mode
 Token exchange test passes with generic config
 Backward compatible - integrated mode still works

Chris Coutinho f34366a260 feat: Add Keycloak OAuth provider support with refresh token storage
Implements Keycloak as an external OIDC provider following ADR-002
architecture for background job authentication using offline_access.

## Features

- Keycloak OAuth provider with PKCE and offline_access support
- Refresh token storage with Fernet encryption
- Token verifier for both JWT and opaque tokens
- Multi-client validation (realm-level trust)
- Sample configuration for Keycloak integration

## Implementation

### OAuth Provider (keycloak_oauth.py)
- Authorization Code Flow with PKCE
- Refresh token exchange
- OIDC discovery endpoint support
- Token validation with JWKS

### Token Storage (refresh_token_storage.py)
- Encrypted storage using Fernet symmetric encryption
- SQLite backend for persistence
- Token rotation support
- Per-user token management

### Token Verifier Updates
- Support both JWT (self-encoded) and opaque tokens
- JWKS-based JWT signature verification
- Introspection endpoint fallback for opaque tokens
- Scope extraction from both token types

### Configuration
- .env.keycloak.sample: Example configuration with Keycloak URLs
- docs/keycloak-multi-client-validation.md: Realm-level validation documentation
- app-hooks/post-installation/10-install-user_oidc-app.sh: Updated dependencies

## Architecture Notes

- MCP Server is a protected resource (requires OAuth)
- MCP Client initiates OAuth flow and shares refresh tokens
- Refresh tokens enable background operations without admin credentials
- Supports future token exchange delegation when Keycloak implements it

## References

- ADR-002: Vector Database Background Sync Authentication
- RFC 6749: OAuth 2.0 (offline_access, refresh tokens)
- RFC 7517: JSON Web Key (JWK)

Chris Coutinho 1e877f17f7 test: Replace persistent OAuth client cache with session-scoped fixtures
Remove file-based caching of OAuth client credentials and implement automatic
client lifecycle management for test fixtures.

Changes:
- Add RFC 7592 client deletion function in auth/client_registration.py
- Remove cache_file parameter from _create_oauth_client_with_scopes helper
- Update all OAuth credential fixtures to use yield/finalizer pattern
- Add automatic client cleanup at end of test session (best-effort)
- Remove persistent .nextcloud_oauth_*.json cache files

Benefits:
- No persistent cache files cluttering repository
- Fresh OAuth clients created for each test session via DCR
- Automatic cleanup attempts (RFC 7592 DELETE endpoint)
- Cleaner test environment with proper fixture lifecycle

Note: Client deletion may fail due to Nextcloud authentication middleware
(logged as warning). The key improvement is removing persistent cache files.
OAuth clients may accumulate in Nextcloud but can be cleaned manually.
