Lemenzo Phone v15.3.1 — Lemenzo Messenger integration fix

Problem:
One SMS path in PhoneNumberInteraction created a generic implicit ACTION_SENDTO sms: intent.
Most other Lemenzo Phone messaging paths already used IntentUtil.getSendSmsIntent(), which pins
the target package to com.lemenzo.messenger.

Fix:
PhoneNumberInteraction now also uses IntentUtil.getSendSmsIntent(phoneNumber).

Result:
All located Lemenzo Phone SMS launch paths now route through the same Lemenzo Messenger helper.
Lemenzo Messenger ComposeActivity already exports ACTION_SENDTO for sms/smsto/mms/mmsto and
parses the recipient from the URI.
