First step of milestone 461 (MCP server). A token is the credential an MCP client presents as `Authorization: Bearer stw_…` to act as its user. - api_tokens table (0026): sha256 hash only, display prefix, role ceiling, expiry, revocation, throttled last_used_at. - steward/core/api_tokens.py: mint, list, revoke, resolve. Resolution re-reads the user's current role and acts with the lower of that and the token's ceiling, so demoting or disabling a user weakens or kills their tokens with nothing to revoke by hand. - /ai-access/ (sidebar → Automation → AI access): every user manages their own tokens, can't grant above their own role, sees the token once. Session-only: a share-link viewer is refused. Create and revoke are audited. - Integration tests drive the routes against real Postgres so their transactions run for real (#884 escaped CI behind a mocked session). Task #4965 "MCP-1 — Personal API tokens". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
