"""Teste US-007 (PRD 3.6): bifa "auto-send" devine un comutator cu doua stari,
etichetat pe COADA (nu pe trimitere).

Framing decis la poarta autoplan (UC-A): "Pune automat in coada" / "Tine pentru
verificare". NU "Automat/Manual" (risc de send-safety peste declaratii ireversibile).
`name="auto_send"` pastrat cu semantica de prezenta (checkbox value="true"):
bifat -> auto_send True, nebifat -> absent -> False. Zero atingere backend, identic
cu ambele parsere existente (`Form(bool)` la /mapari si `bool(form.get())` la preview).
