guard double-apply, hide error msg, wohnungen polish, bitwarden block

- /actions/apply now no-ops (returns fresh partial) when a running
  application exists for this user+flat, or when a previous one succeeded.
  The list button was already visually disabled; this closes the direct-POST
  and double-click loopholes
- Drop the one-line error message under flat entries in the list
  (bewerbung_detail still shows the full message + the forensic ZIP report)
- Strip "min morgens" commute chip from the list; alert._flat_payload sends
  an empty connectivity dict so Maps.calculate_score is no longer called on
  every flat. Maps.calculate_score + Flat.connectivity stay in the codebase
  for easy re-enable (one-line swap in _flat_payload)
- List entry shows "vor 23 min" instead of "entdeckt vor 23 min"
- Bitwarden: rename profile email/immomio fields to opaque names
  (contact_addr, immomio_login, immomio_secret) + add data-bwignore across
  every settings form / input. Server-side update_profile maps the new
  field names back to the existing DB columns
