fix: prevent package removal during web update and fix zapret2 installation

- Fix package postrm scripts to strictly require \ to be 'remove' or 'purge' before running cleanup, preventing destructive cleanup when opkg runs postrm with empty arguments during reinstalls/upgrades.
- In action.uc install_files, ensure tachyon backend package is installed before luci-app-tachyon to prevent opkg dependency removal races.
- In action.uc install_zapret2, ensure ::1 localhost exists in /etc/hosts before package installation to prevent nftables IPv6 resolution errors, and cleanly stop/disable standalone zapret2 daemon.
- In zapret2 provider common.uc and nfqueue runtime.uc, automatically resolve required blob binary payloads and default filter parameters for strategies.
- In fe-app-tachyon, add 'access denied' / 'Доступ запрещён' to transient RPC error patterns and track install_version as self-update so rpcd reload during self-update does not abort the progress modal with an error.
- In tests/package_lifecycle.sh, avoid grep -q in pipefail pipelines to prevent upstream SIGPIPE failures.
