Walkthrough

The change adds shared redirect URI validation. It accepts HTTPS and localhost HTTP URLs, rejects unsupported schemes and non-localhost HTTP URLs, and applies the rule to callback URL construction and authorization-link validation.

Changes

Redirect URI validation

Layer / File(s)	Summary
Redirect validation and callback construction web/src/utils/authorizationScopes.ts, web/__test__/authorizationScopes.test.ts	The utilities accept https: URLs and http: URLs on localhost. buildCallbackUrl rejects other URLs before adding callback parameters. Tests cover accepted and rejected inputs.
Authorization-link validation web/src/composables/useAuthorizationLink.ts, web/__test__/composables/useAuthorizationLink.test.ts	useAuthorizationLink now uses isValidRedirectUri. Tests cover HTTPS, localhost HTTP, non-localhost HTTP, and javascript: URLs.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 9b7b1

The redirect validation behavior is covered, but the changed test code does not meet repository test conventions. Address these small test maintenance issues before merge.

asynchronous rejection and assert only that it throws, using the promise-based
rejects.toThrow() matcher without an error-message argument.
