Chris Coutinho d16bcdcfbb feat: Implement ADR-004 Progressive Consent foundation components
- Token Broker Service manages Nextcloud access tokens with audience validation
- Implements short-lived token caching (5-minute TTL) with early refresh
- Enhanced token storage schema with ADR-004 fields (flow_type, audience, provisioning)
- MCP provisioning tools for explicit Flow 2 resource authorization
- Comprehensive unit tests for Token Broker Service (14 tests, all passing)
- Environment configuration for Progressive Consent mode

This implements the foundation for the dual OAuth flow architecture where:
- Flow 1: MCP clients authenticate to MCP server (aud: "mcp-server")
- Flow 2: MCP server gets delegated Nextcloud access (aud: "nextcloud")

Users must explicitly call provision_nextcloud_access tool to grant resource access,
implementing the "stateless by default" principle from ADR-004.

# ===== AUTHENTICATION MODE =====
# Choose ONE of the following:
# Option 1: OAuth2/OIDC (RECOMMENDED - More Secure)
# - Requires Nextcloud OIDC app installed and configured
# - Admin must enable "Dynamic Client Registration" in OIDC app settings
# - Leave NEXTCLOUD_USERNAME and NEXTCLOUD_PASSWORD empty to use OAuth mode
# - OAuth client credentials are stored encrypted in SQLite (TOKEN_STORAGE_DB)
# - Optional: Pre-register client and provide credentials (otherwise auto-registers)

# ===== ADR-004 PROGRESSIVE CONSENT CONFIGURATION =====
# Enable Progressive Consent mode (dual OAuth flows)
# When enabled: Flow 1 for client auth, Flow 2 for Nextcloud resource access
# When disabled: Uses existing hybrid flow (backward compatible)

# Option 2: Basic Authentication (LEGACY - Less Secure)
# - Requires username and password
# - Credentials stored in environment variables
# - Use only for backward compatibility or if OAuth unavailable
# - If these are set, OAuth mode is disabled
