Fix trunk/messaging #include lines never reaching an existing install's live config

Confirmed live via a real failed test call ("extension not found in context
'intercom'"): Easy Asterisk's entrypoint only regenerates pjsip.conf/
extensions.conf if they don't already exist. Patching the vendor generator
functions (as both pstn-trunk.sh and the earlier SIP MESSAGE work did) only
takes effect on a future full regeneration — a box that already has devices
configured, the normal case, never triggers one on a plain restart, so the
#include lines never actually reached the live files despite the generator
patch succeeding.

Both installers now also patch the live pjsip.conf/extensions.conf directly
(same anchors, idempotent) and force a reload, so the trunk/messaging
dialplan actually takes effect immediately regardless of whether Easy
Asterisk ever regenerates its config on its own.
