Rename asterisk-do service to asterisk-digital-ocean

Renamed services/asterisk-do.sh -> services/asterisk-digital-ocean.sh
(register_service name, install function, install dir, and all prose/
comments) so the whiptail menu shows a clearer, more discoverable name.

Updated the functional cross-references that depend on the old name:
crowdsec.sh's SIP-log auto-detection path and acquisition filename,
caddy.sh's host.docker.internal comment, and the CLAUDE.md/README.md
docs (services table, directory listing, network-wiring example).

Container names, the Docker Compose project name, and the internal
_asterisk_do_* helper function identifiers are left unchanged since
they aren't user-facing and renaming them would add risk for no
benefit.
