fix(linux): restore SELinux service startup with v2.7.2

Upgrade clash_verge_service_ipc and bundled service downloads to v2.7.2,
which labels runtime-installed executables before publication and repairs
existing core labels instead of timing out waiting for service IPC.

Register persistent bin_t rules for production and development service
binaries and cores in the RPM post-install script. Support older semanage
versions, apply rules to existing directories, and warn when optional
SELinux tools are unavailable.
