🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Exercise the production validators instead of duplicate local oracles.

TestWave3RelationTupleFormatting only calls validateEntity; it never calls pkg/tuple.E. The local implementation also omits the strings.TrimSpace behavior in pkg/tuple/tuple.go:214-234, so a production regression can pass this test.

TestWave3PermissionNameValidation has the same problem. Its local oracle accepts -view, view-, _view, and view_ because it checks allowed characters but not alphanumeric first and last characters. Call the production permission validator and add cases for the declared boundary and length rules, plus malformed entities such as user: and user:123:extra.

Also applies to: 29-39

In `@internal/validation/wave3_relation_tuple_test.go` around lines 9 - 15, The
wave 3 validation tests duplicate incomplete local validators instead of
exercising production behavior. Update TestWave3RelationTupleFormatting to call
pkg/tuple.E and cover whitespace trimming plus malformed entities such as user:
and user:123:extra; update TestWave3PermissionNameValidation to call the
production permission validator and add cases for alphanumeric boundary and
declared length rules, including rejecting -view, view-, _view, and view_.
