Problem: `M.submit` gave no UI feedback between credential entry and
final result, leaving users staring at a silent hang for 10-30s.
Solution: Add `STATUS_MSGS` map and emit an immediate `vim.notify` on
submit start. Pass an `on_status` handler to `scraper.submit` that fires
a notification for each phase (`checking_login`, `logging_in`, etc.).
