fix(ui): log global errors silently instead of popping a toast + overlay

The global error handler (Vue errorHandler + window error + unhandledrejection)
fired a red 'Something went wrong: <raw msg>' toast AND an auto on-device overlay
on every caught error — deliberately loud for bug-bash, but it surfaces benign,
non-actionable noise (e.g. a transient RPC rejection during a ws reconnect, or
the service worker failing to register over a self-signed cert) right in the
user's face.

Demote the catch-all to SILENT capture: keep console.error + the
window.__archyErrors ring buffer, and expose the screenshot-able overlay
on-demand via window.__archyShowErrors() — but never auto-pop. Components that
need to report a specific, actionable failure still call toast.error() directly.

Also filter known-benign environmental noise (PWA service-worker registration
failing over a self-signed cert — needs a trusted cert, #56) so it doesn't even
occupy a ring-buffer slot and push out real errors.
