fix(ci): add cargo clean and artifact removal before packaging; bump to 1.1.7

- Insert 'Clean previous build artifacts' step (cargo clean + rm old .deb) before Build Debian package in both build-deb and build-deb-u2204 jobs. - Bump version to 1.1.7 to ensure a clean build from scratch. - Update debian/changelog with 1.1.7-1 entry.
fix(certs): replace encrypted CA with unencrypted ECDSA P-256 CA
