feat(pia): add PIA login-and-add WireGuard outbounds (#6272)

* feat(pia): add login-and-add WireGuard outbounds (#2)

* fix(pia): keep PIA outbounds identifiable after the editor strips hostname

The outbound editor drops piaHostname, so last-segment matching failed for hyphenated servers. Identify rows by the computed tag, re-encrypt stored tokens onto the active key, skip unusable catalog rows, and always release the catalog refresh latch.
