Robustness:
- Surface 401/404 stream failures via _set_fatal_error() so the gateway's
runtime status reflects 'fatal: ntfy_unauthorized' / 'ntfy_topic_not_found'
instead of staying 'connected' when the reconnect loop halts. Matches
the pattern in whatsapp / telegram / sms adapters.
- Strip whitespace from auth tokens so pasted tokens with trailing
newlines don't produce malformed Authorization headers.
Simplicity:
- Extract _build_auth_header() and _truncate_body() to module-level
helpers, used by both NtfyAdapter and _standalone_send. Removes the
duplicated auth/truncation logic between the two paths.

Tests: 78/78 (+ 10 new robustness tests covering token hygiene, fatal
error propagation for 401/404, and the _truncate_body helper).
