classify daemon login errors and surface localised dialogs

The daemon returns gRPC errors whose message is a wrapped mgm + JWT
stack (e.g. "invalid jwt token, err: token could not be parsed: ...").
Showing that in a native dialog is unreadable. Connection now maps the
substrings it recognises to a ClientError{code, short, long} so the UI
can render a localised summary plus a Details: block carrying the raw
daemon text. formatErrorMessage on the TS side reads the structured
payload from Wails' Error.cause (or the JSON-stringified Error.message)
and falls back to plain Error.message for callers not yet migrated.

Also bumps Wails to v3.0.0-alpha.95.
