Delete coredata.CookiePattern and all associated CRUD methods,
rename shared types (CookiePatternOrderField, CookiePatternFilter,
CookiePatternMatchType) to TrackerPattern equivalents, and migrate
all API surfaces (GraphQL, MCP, CLI, n8n) to tracker_pattern naming.
The worker was already migrated in the base branch; this commit
completes the removal by dropping the old GraphQL schema/resolvers,
service methods, CLI commands, and n8n operations that operated on
the legacy cookie_patterns table.
