Greptile Summary

This PR reverts the Metrics Studio, platform administration, gated-signup, and metric-draft functionality introduced by the preceding commit.

• Removes Metrics Studio routes, workers, persistence models, frontend pages, and tests.
• Removes platform-admin organization controls and reference-code-gated signup.
• Restores the prior metric management API and frontend.
• Also removes disabled-organization enforcement from authentication paths, allowing previously suspended tenants to authenticate again.

Confidence Score: 4/5

The authentication regression must be fixed before merging because organizations disabled before this revert can regain access through every supported credential flow.

Applied migrations are not downgraded when their files are deleted, but the revert removes every runtime check of the retained organization-disabled state before issuing or accepting organization-scoped principals.

Files Needing Attention: app/core/auth/api_key.py, app/core/auth/local.py, app/core/auth/oidc_common.py, app/api/v1/routes/auth.py

Security Review

Disabled organizations retained in upgraded databases can authenticate again through API keys, local sessions, OIDC, refresh tokens, and organization switching because all organization-active guards are removed. How this was verified: The changed authentication paths construct or issue organization-scoped principals without any remaining check of the persisted organization-disabled state.

Important Files Changed

Filename	Overview
app/core/auth/api_key.py	Removes the organization-active guard, allowing existing keys for previously disabled tenants to authenticate.
app/core/auth/local.py	Removes the disabled-organization check from local bearer-token authentication.
app/core/auth/oidc_common.py	Allows OIDC identities mapped to previously disabled organizations to receive principals.
app/api/v1/routes/auth.py	Removes disabled-organization filtering from login, refresh, and organization-switching flows.
app/api/v1/routes/metrics.py	Reverts draft lifecycle endpoints and filtering; persisted draft rows may remain but are disabled.
app/models/database.py	Removes platform administration, draft lifecycle, and Metrics Studio ORM models while deployed databases may retain their schema.
frontend/src/App.tsx	Removes platform administration and Metrics Studio routes and restores the previous metrics pages.
app/migrations/057_platform_admin.py	Deletes the migration file without downgrading already-upgraded databases, preserving prior disabled-organization state.

Disabled organization access bypass

If a database contains an organization disabled before this revert, API-key, local, OIDC, refresh-token, and organization-switching flows now issue or accept organization-scoped principals without checking the retained disabled state, causing suspended users and clients to regain access to the tenant's routes and data.

How this was verified: Every changed authentication path reaches principal construction or token issuance without any remaining organization-active guard.
