fix(telegram): use idempotent retry context for delete/reaction (#96612)

reactMessageTelegram and deleteMessageTelegram passed context: "send" to
isRecoverableTelegramNetworkError, which disables message-snippet matching
(allowMessageMatch defaults to false only for "send"). Both operations are
idempotent (setMessageReaction / deleteMessage are safe to repeat), yet a
transient snippet-only network error (e.g. "socket hang up", "undici network
error" with no error code) was not retried — stricter than polling/webhook/
unknown, which all default allowMessageMatch to true. Users saw spurious
reaction/delete failures on transient network errors.

Add delete | react to TelegramNetworkErrorContext (additive) and use them at
the two callers. The helper default (context !== "send") is unchanged, so
delete/react now match polling/webhook/unknown. sendMessage keeps "send".
