Replace the loose NotificationDefaults intermediate type and 'as NotificationFormData'
cast with an exhaustive buildDefaults() helper that narrows each branch of the
discriminated union explicitly. TypeScript now infers the return type correctly from
the discriminated union without any casts, satisfying strong typing for all channels
(email, slack, discord, webhook, pager_duty, teams, matrix, telegram).
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
