Per @ajhollid review: define defaults up-front with a NotificationDefaults type
and eliminate the trailing else branch entirely. The if/else-if blocks only
override when the type is matrix or telegram.
- useNotificationForm: replace nested ternary with if/else if/else block
- TelegramProvider: type error as unknown and access properties safely
via instanceof checks instead of casting to HTTPError
