feat(clients): show short HWID fingerprint in admin device list (#6464)

* feat(clients): show short HWID fingerprint in admin device list

Expose a 12-char prefix of the stored hwid_hash in the admin HWID list API and UI so admins can distinguish devices without querying the database. Full hashes and raw HWIDs remain unexposed.

Fixes #6359

* ci: retrigger release matrix after 386 dependency download flake
