trunks: CRUD API, PJSIP trunk config, live registration status, Trunks page

voip.ms-first trunk form with the portal checklist, POP server list and Test button; passwords are write-only and encrypted. Registration and IP-auth trunks render per 03 §5.3 (TCP/TLS add ;transport=). The API refuses a server name that doesn't resolve and transports that are off, because either makes Asterisk drop the trunk. Live state: registration from PJSIPShowRegistrationsOutbound (re-read on every Registry event: two sub-accounts on one server share Username/Domain), reachability from PJSIPShowEndpoint and trunk ContactStatus (static contacts aren't in PJSIPShowContacts). Trunk state is admin-only. Dashboard gets a "Trunks up" card. trunk-test.ts (in pnpm test:asterisk) runs a fake voip.ms (second Asterisk): the good trunk registers, a wrong password is Rejected, qualify reaches the provider; its recorded AMI drives the unit tests. scripts/e2e/m3-t1.mjs does the same through the UI. The acceptance check with a real voip.ms sub-account is still to do. Tests: settle() now awaits an apply instead of a fixed sleep (flaked under full-suite load). Task: M3-T1
