fix(auth): stop IDOR 'default' guard from 401-ing the single-user owner into a login loop (#31)

Fixes the web UI getting stuck on the password login screen even when no
password is configured: route IDOR-017 guards equated userId==='default'
(the only id a single-user install assigns) with 'anonymous' and 401'd the
owner, and the frontend 401 handler escalated that into a forced /login redirect.

Also repairs pre-existing main breakage that was blocking CI once the build was
fixed: 21 TS build errors (canvas/pulse/voice/claw), 134 stale unit tests across
core+gateway, Playwright headless/E2E config, repo-wide prettier drift, and a
.gitattributes to enforce LF.
