api/v2: stop echoing request values in error responses
...
huma sets an unexpected property's value to the whole request object.
A refused policy, or another 400, now carries its reason in message,
and a failed test run one data entry per failing test naming its src.

policy/v2: check grant and nodeAttrs user references on write

Validation now refuses every input that reached the SetPolicy compile
failure, so restoring the previous policy there is defensive only.

policy/v2: warn once at load about malformed nextdns attrs

policy: offer exit routes only to viewers whose rules reach the internet
...
Every destination overlaps /0, so any rule offered a peer's exit routes.
They now need a rule to the internet, the test exit-node visibility
uses; via steering defers them to a regular grant only on that test.

policy: reduce merged destination prefixes to the node's own addresses
...
Adjacent node addresses merge into one prefix, and each node's filter
kept all of it. A prefix made only of node addresses now shrinks to the
node's own; a prefix the policy wrote, or one the node routes, stays.

api, policy/v2: refuse route prefixes with host bits

Routes are matched as written, so such a prefix never equals the one a
client announces. The approval APIs answer 400 and autoApprovers refuses
it at load and write, with Tailscale's text.
