feat: Absender/Titel frei wählbar, kein "Notruf"-Default mehr (0.1.2)

"Notruf" war als Library/CLI-Default falsch — das gehört in die Bridge-Config,
nicht ins Allzweck-Tool. Jetzt:

- kein eingebauter Default-Absender; ohne Angabe nutzt seven.io den
  Kontostandard-Absender (send_sms lässt "from" dann weg)
- CLI --from für SMS (Absender/Titel) und Voice (Caller-ID); zusätzlich
  $SEVEN_SMS_FROM / $SEVEN_VOICE_FROM als persistenter Default
- Tests: Default ohne Absender, per-call-Override, CLI --from + Env (19 gesamt)
- README: Absender/Titel dokumentiert

Die Bridge übergibt sms_from="Notruf" weiterhin explizit -> Voice Assistant
unverändert.
