Walkthrough

This PR applies broad cross-cutting changes: multiple email templates migrated to Tailwind-based @react-email components and package updates; email transports (SMTP/AWS SES) now await rendered HTML; invite schema and several email props updated. It adds a Redis-backed magic-link rate limiter and integrates rate-limiting into the login magic flow. The run-engine gains repair/reporting features, new RunQueue concurrency/clear APIs, worker repairSnapshot, and many internals updated (span/event APIs, span presenters, event repository). Webapp routes and presenters were tightened to enforce membership checks; env schema gained LOGIN_RATE_LIMITS_ENABLED; personal access token revoke now requires userId. Helm/docker images and chart/values updated for legacy Bitnami images and new webapp init/tokenSyncer images. Miscellaneous type and import refinements across the codebase.
