When a user signs up with an email they don't own and sets a password,
that password remains valid even after the real owner later signs in via
OAuth. This means the original registrant — who never proved ownership
of the email — retains working credentials on the account. This change
closes that gap by rotating the password to a random value whenever an
unconfirmed user completes an OAuth sign-in.
The check (`oauth_user_needs_password_reset?`) is evaluated before
`skip_confirmation!` runs, since confirmation would flip `confirmed_at`
and mask the condition. If the user was unconfirmed, the stored password
is replaced with a secure random string that satisfies the password
policy. This applies to both the web and mobile OAuth callback paths, as
well as the sign-up path where the password is rotated before the reset
token is generated.
Users who lose access to password-based login as a side effect can
recover through the standard "Forgot password" flow at any time. Since
they've already proven email ownership via OAuth, this is a low-friction
recovery path
This makes account signup enforcement consistent when signup is disabled
at the installation level. Email signup and Google signup now stay
blocked regardless of whether the config value is stored as a string or
a boolean.
This effectively covers the config-loader path, where `YAML.safe_load`
reads `value: false` from `installation_config.yml` as a native boolean
and persists it that way.
- Normalized the account signup check so disabled signup is handled
consistently across config value types.
- Reused the same check across API signup and Google signup entry
points.
- Added regression coverage for the disabled-signup cases in the
existing controller specs.
