Previously, we had a single label, `reserved:world`, applied to all CIDR (non-cluster) identities. With cilium#22625, this is no longer the case; CIDR identities get either `reserved:world-ipv4` or `reserved:world-ipv6` labels **in dual stack clusters**. This PR updates the `toEntities: world` selector to select *all* world entities, as it worked previously. It does so by expanding the set of selectors underlying the `world` entity. No other magic in the SelectorCache or policy engine is required. Fixes: cilium#29666 Fixes: a94fa56 Signed-off-by: Casey Callendrello <cdc@isovalent.com>

the ipsec upgrade test is still failing, because it downgrades to v1.15 which still has this bug. |
