fix: webhook:close button not working due to channel check timeout

Channel checker middleware called bot.get_chat_member() which could
timeout (60s), causing callback.answer() to fail with "query too old".

Skip channel check for lightweight UI callbacks (webhook:close,
ban_notify:delete, noop). Also answer callback before delete attempt
and add fallback to remove keyboard if delete fails.
