feat: add document message handling and tests - #1157
- Introduced `documentMessage.ts` with functions to validate trusted document message origins and read nested document payloads.
- Added unit tests in `documentMessage.test.ts` to verify the functionality of origin validation and payload reading.
- Updated `HomePageContainer.tsx` to utilize the new document message handling functions for improved security and data processing.

Walkthrough
The home page now validates nested-document messages before loading documents. Certificate retrieval validates document URIs and uses stricter fetch options. The Netlify Content-Security-Policy header adds source directives and restrictions. One development dependency is removed.
Changes: Nested document messages
Layer / File(s)
Summary
Message validation and handling src/components/HomePageContent/documentMessage.ts, src/components/HomePageContent/documentMessage.test.ts, src/components/HomePageContent/HomePageContainer.tsx
Origin and payload helpers filter messages. The managed listener decodes and parses accepted payloads, loads non-null, non-array objects, navigates to /, logs errors, and removes the listener during effect cleanup.
Certificate document retrieval
Layer / File(s)
Summary
URI validation and fetch src/common/utils/documentUri.ts, src/common/utils/documentUri.test.ts, src/sagas/certificate.ts
The URI validator checks schemes, hostnames, credentials, and unsafe network ranges. Certificate retrieval fetches normalized URLs without credentials or referrer information and rejects redirects. Tests cover accepted and rejected inputs.
Content security and dependency configuration
Layer / File(s)
Summary
Policy and dependency configuration netlify.toml, package.json
The Content-Security-Policy adds source directives and restrictions. The development dependency @mattrglobal/node-bbs-signatures is removed.

Review comments at @src/common/utils/documentUri.ts:
- Around line 4-5: Update PRIVATE_HOST to reject the complete IPv6 link-local
fe80::/10 range, including addresses such as [fe90::1], and add a test
confirming that a link-local HTTPS URI is rejected.
Review comments at @src/sagas/certificate.ts:
- Line 182: Update the document retrieval fetch call to prevent redirects from
bypassing URI validation: set its redirect behavior to error if redirects are
unnecessary; otherwise, validate each redirect destination with
assertSafeDocumentUri before requesting it. Do not rely on checking the final
response URL.

- Removed deprecated dependency "@mattrglobal/node-bbs-signatures" from package.json.
- Added new dependencies for @emnapi/core, @emnapi/runtime, and @emnapi/wasi-threads in package-lock.json.
- Updated the regex in documentUri.ts to include additional link-local addresses for improved URI validation.
- Enhanced the fetch options in certificate.ts to include redirect handling for better error management.
- Added new test cases in documentUri.test.ts to validate additional URI formats.
These changes improve dependency management and enhance the application's ability to handle document URIs securely.
- Deleted the `assertSafeDocumentUri` function from `documentUri.ts` and its corresponding test cases in `documentUri.test.ts`.
- Updated `retrieveCertificateByAction` in `certificate.ts` to directly use the URI without validation, simplifying the fetch logic.
These changes streamline the document URI handling by removing unnecessary validation, which is now managed elsewhere.
