redesign

[evrendom]

Summary

This is a cumulative redesign branch. It introduces the new dashboard shell and redesign system, moves the main analytics experience onto redesign-native pages, and includes the supporting analytics, auth, and platform work that branch depends on.

What changed

• adds the redesign dashboard foundation: new shell, sidebar, shared date range controls, chart/table/card primitives, and route structure alongside the preserved legacy dashboard
• adds redesign-native pages for sessions, projects, costs, team, errors, ROI, profile, invitations, organization management, create organization, and session detail
• promotes Costs, Errors, and ROI into the redesign flow, with exact-range data handling for the redesign errors and ROI pages and a dedicated costs dashboard endpoint
• expands analytics plumbing across web, API, and CLI, including semantic dashboard tracking, lifecycle/upload analytics, and supporting product analytics contracts
• includes supporting platform work already in the branch: session access control, org membership checks, query/input hardening, ingest rate limiting, invitation resend flows, device-code auth in the CLI, Chatwoot support, and related schema/migration/test updates

Verification
