v1.30.1-fips: minor fixes, use Go 1.26

This release includes no new features, but bumps the minimum Go version from 1.24 to 1.26. It also includes several fixes for test flakiness (thanks @mohqas!).

This is the FIPS version of the v1.30.1 release, and has identical changes to that release, but remains stripped of all cryptography code.
