fix(oauth): Add missing MCP server OAuth scopes (#938)

## Problem
Twig wasn't requesting all OAuth scopes that the PostHog MCP server supports, causing MCP tools that rely on those scopes to fail.

Missing scopes: `action:read`, `action:write`, `error_tracking:write`, `event_definition:write`, `logs:read`, `warehouse_view:read`.

## Changes
- Added 6 missing MCP server OAuth scopes to the Twig app's OAuth configuration
- Sorted scopes alphabetically for consistency
