fix(api): require access codes and limit sizes on helper routes
- Shared checkAccessCode for validate-diagram, validate-model, parse-url, verify-access-code - parse-url: 5 MB streamed body limit; validate-diagram: 5 MB image limit - validate-model refuses redirects when private URLs are blocked - Admin settings state shared across module instances via globalThis - Server model ids: unique slugs (non-ASCII names encoded), duplicates rejected - Panel Bedrock credentials stored as ADMIN_AWS_* so the DynamoDB client keeps its own - Locale redirect keeps basePath and query; EdgeOne function drops open CORS and checks the access code - Providers payload reports whether .env sets a default model
