fix: resolve API endpoint 404 errors by correcting double path issue
- Fixed duplicate /api/v1/ paths in all endpoint calls - Updated all endpoints to use relative paths when base URL already includes /api/v1 - Changed endpoints from /api/v1/workflows to /workflows throughout codebase - Fixed src/server.ts, src/index.ts, and src/services/n8nApi.ts - Bumped version to 0.10.3 - Resolves 404 errors in list_workflows and all other MCP tools
