[Feature]: Add a tooltip/hint to the "Password" field in the client form clarifying which protocols use it (#5809)

* feat(clients): clarify which protocols use the Password and Hysteria Auth fields

Add tooltips to the Password and Hysteria Auth Form.Items in the client
form, explaining that Password is only consumed by Trojan and Shadowsocks
(ignored for VLESS, VMess, Hysteria, WireGuard) and that Hysteria Auth is
the credential Hysteria actually uses. Adds passwordDesc/hysteriaAuthDesc
keys to all 13 locale files, following the existing limitIpDesc/totalGBDesc
tooltip convention.

Closes #5803

* test(clients): assert Password/Hysteria Auth tooltip hints render
