Secure Intercom Ubuntu Beta R5 — activation renewal candidate

End calls, quit Baby Picobot bridges and close Secure Intercom.
Run sh install.sh in your graphical desktop account, without sudo.
The previous app folder is retained. Identity, contacts, activation and audio
settings are preserved; keyring and package checks must pass first.

Renew activation / Get a code opens the renewal page for the saved recipient.
Follow the browser instructions, then paste the emailed or administrator-issued
code into Secure Intercom and choose Complete setup. Do not reset your identity.
Browser instructions clear when a code is submitted. Actual activation results
are shown in the status field. Renewal navigation is disabled during calls/setup.

Check for updates, invitation deletion and the existing audio behavior remain.
This candidate needs desktop, renewal and two-way-call acceptance before publishing.
