Devin Carr 2253eeeb25 TUN-10834: Bump Go toolchains to 1.26.8
Update CI and standard container builders to Go 1.26.8.

Add coverage for Go 1.26's stricter net/url host parsing, rejecting
unbracketed IPv6 addresses and repeated port separators in origin URLs.
Retain existing Access bare-IPv6 normalization behavior.

Closes TUN-10834
