feat(notifications): custom test-notification text in web (#563)

[axisrow]

Addresses the «Тест уведомлений» parity gap from #563.

Проблема

Одно и то же действие вело себя по-разному: CLI notification test --message "..." позволяет задать свой текст, а кнопка «Тест» в вебе всегда слала фиксированную строку.

Решение

• dispatcher _handle_notifications_test: использует payload["text"], если задан и непустой; иначе — дефолтное сообщение.
• web handle_test_notification: читает необязательное поле формы text и прокидывает его в payload только если оно непустое (пустое → дефолт диспетчера).
• шаблон settings/_notifications.html: добавлено необязательное текстовое поле рядом с кнопкой «Тест».

CLI уже поддерживал --message, поэтому правок там не требуется — теперь поведение совпадает.

Примечание: остальные пункты #563 (collect через слой-посредник, интерактивный agent chat, context rebuild, окно dry-run) — отдельные расхождения уровня архитектуры; этот PR закрывает изолированный и безопасный пункт про тест уведомлений.

Проверка

• ruff чисто; dispatcher + web notifications + CLI notification тесты — 191 passed (включая новые: кастомный текст в payload, пустой текст → пустой payload, дефолт диспетчера).

PR review

I read the full diff plus the wrapper/CLI/agent code that surrounds it.

Overall: 👍 solid PR, correctly scoped and tested

The core fix is right:

• Dispatcher (telegram_command_dispatcher.py:858): str(payload.get("text") or "").strip() or "<default>" correctly handles None, missing key, empty string, and whitespace-only — all fall back to the default. ✓
• Web handler: reads text, strips, passes payload={"text": text} only when non-empty. ✓
• Template: adds optional input alongside the button. ✓
• Tests: 3 new + 1 reinforced assertion (the existing dispatcher test now also asserts the default message is sent). ✓

Issues worth flagging

1. Incomplete parity claim (medium)

The PR description says "CLI уже поддерживал --message, поэтому правок там не требуется — теперь поведение совпадает." That's true for CLI ↔ Web, but there's a third codepath that's still hardcoded:

src/agent/tools/notifications.py:101–117

@tool("test_notification", "Send a test notification message via the bot", {})
async def test_notification(args):
    ...
    await svc.send_notification("🔔 Тестовое уведомление от агента")

So:

• CLI notification test --message ... → custom text ✓
• Web button → custom text (after this PR) ✓
• Agent test_notification → still hardcoded string ✗

This is a tiny addition (a text annotated arg + pass to send_notification) and would actually complete the parity. The PR could either close it here or call it out explicitly as a follow-up. The current PR text leaves a reader thinking parity is done.

Also worth noting: the CLI uses NotificationService.send_notification() directly, while the web button goes through the notifications.test dispatcher command. Two paths reach the same notifier — fine, but the dispatcher fix only benefits the web/agent route. Not a bug, just an observation.

2. Test name is mildly misleading (low)

test_test_notification_blank_text_omits_payload asserts kwargs["payload"] == {}, but the handler passes payload=None. The empty-dict comes from _enqueue_notification_command's payload or {} normalization (handlers.py:112). The test name says "omits" but what's tested is "normalized to empty". Either rename to ..._falls_back_to_empty_payload or assert payload=None was the value the handler passed. Not a blocker — passes today, behaves correctly.

3. Dispatcher one-liner is dense but correct (low/nit)

text = str(payload.get("text") or "").strip() or "✅ Тест уведомлений: соединение установлено"

The or-chain works because of Python falsy semantics; if a future caller passes a non-string (e.g., a list), str() would stringify it into the notification. None of the current callers do that, so it's theoretical. If you want to be strict:

raw = payload.get("text")
text = (raw.strip() if isinstance(raw, str) else "") or "✅ Тест уведомлений: соединение установлено"

Optional cleanup.

4. Template — inline style (nit)

style="max-width:20rem" on the input — fine but slightly out of step with utility-class patterns. Skim other settings templates; if they use inline styles, keep as is. Cosmetic.

Verdict

Ship it after deciding on #1 (close the agent gap in this PR, or amend the PR description to call it a known remaining gap). Items 2–4 are nits — none block merge.
