Kristoffer Dalby 12a34f3895 policy/v2: implement grant validation rules matching Tailscale SaaS ...

Add five categories of grant validation that Tailscale enforces:

1. Capability name format: reject URL schemes (://) and restrict
   tailscale.com domain to an allowlist of user-grantable caps.

2. Grant-specific autogroup:self: reject wildcard (*) sources with
   autogroup:self destinations (stricter than ACL rules since * includes
   tags which cannot use autogroup:self).

3. App + autogroup:internet: reject app grants targeting
   autogroup:internet.

4. Raw default route CIDRs: reject 0.0.0.0/0 and ::/0 as grant
   destinations, requiring "*" or "autogroup:internet" instead.

5. Via field: non-tag values (e.g. autogroup:tagged) are caught at
   unmarshal time by Tag.UnmarshalJSON validation.

This resolves 23 ERROR_VALIDATION_GAP + 1 via validation test, reducing
the grant compat skip list from 28 to 5 remaining tests.
