fix(httpauth-jwt): WithJSONNumber in Verify, JSON errors in AuthMiddleware, bump httpauth v1.0.2 (#1)

Browse Source 
Pass jwt.WithJSONNumber() to jwt.Parse in hmacSigner.Verify, rsaSigner.Verify, and
rsaPublicVerifier.Verify. JWT numbers (including permission bitmasks) are now decoded
as json.Number instead of float64 — exact parsing for all integers including
math.MaxInt64 (the ADMIN wildcard mask). Float64 would round MaxInt64 to 2^63 and
overflow back to math.MinInt64 on cast to int64.

AuthMiddleware now calls httpauth.WriteJSONError for all 401 responses instead of
http.Error. Standardizes the error format across the full httpauth-* middleware stack:
AuthMiddleware (httpauth-jwt), EnrichmentMiddleware, and AuthzMiddleware (httpauth)
all produce {"code":"UNAUTHENTICATED"|"PERMISSION_DENIED"|"INTERNAL","message":"..."}.

Update two existing tests (TestIssueTokenPair_CustomClaims,
TestRefreshTokenPair_CustomClaimsInNewToken) to assert json.Number instead of float64
— they were correct before WithJSONNumber, now reflect the actual decoded type.

Add TestVerify_JSONNumberPreservesMaxInt64: issues a token with math.MaxInt64 as a
bitmask, verifies it, and asserts the decoded value is exactly math.MaxInt64 via
json.Number.Int64() — proving no float64 round-trip occurs.

Add TestAuthMiddleware_UnauthorizedJSON: asserts the 401 response is
Content-Type: application/json with body {"code":"UNAUTHENTICATED","message":"..."}.

Bump httpauth dependency to v1.0.2.
