fix: navigate telegram E2E tests to channels subtab (#1408)

* fix: navigate telegram E2E tests to channels subtab

wasm_channel extensions (like telegram) are now rendered in the
Settings → Channels subtab, not the Extensions subtab. Update
test_telegram_hot_activation to navigate there and use the correct
card selector. Also mock /api/gateway/status which loadChannelsStatus
fetches.

* fix: select telegram card by name, not first card in channels subtab

Built-in channel cards (Web Gateway, HTTP, etc.) render first in the
channels subtab content, so .first matches them instead of the
telegram extension card. Select by has_text="Telegram" to target
the correct card.

* refactor: make gateway_status_handler parameterizable in mock helper

Address review feedback: extract default gateway status handler and
accept an optional gateway_status_handler kwarg in mock_extension_lists
for test flexibility.
