bump vulnerable transitive dependencies to patched versions (#1266)

- kubernetes: ==34.1.0 → >=35.0.0 (unlocks urllib3 v2.x support)
- urllib3: >=2.1.0,<2.4.0 → >=2.6.3 (CVEs: decompression bombs, redirect bypass)
- cryptography: >=42.0.4 → >=46.0.7 (subgroup attack, buffer overflow, DNS CVEs)
- requests: stays <2.32; blocked by docker-py 6.x Unix socket dependency
  (fix: upgrade docker to >=7.0 and requests to >=2.33.0 in a follow-up)
