fix(hardened): remove PURL qualifier double-encoding and enable Hummingbird URL

[ruromero]

Summary

• Remove redundant URLEncoder.encode() in HardenedImageResponseHandler.containerRefToPackageRef() — the PackageURL constructor already encodes qualifier values, so this was causing double-encoding of the repository_url qualifier
• Uncomment the trustedcontent.recommendation.hardened.url configuration property to enable Hummingbird integration

Test plan

• Verify hardened image PURLs contain correctly-encoded repository_url qualifiers (no %25 double-encoding)
• Verify Hummingbird URL config property is active and the provider initializes on startup
• Run existing integration tests for hardened image recommendations

Summary by Sourcery

Fix hardened image recommendation integration by correcting PURL qualifier encoding and enabling the Hummingbird provider configuration.

Bug Fixes:

• Prevent double-encoding of hardened image PURL repository_url qualifiers by avoiding redundant URL encoding.

Enhancements:

• Enable the hardened (Hummingbird) recommendation provider via application configuration.
• Update the generated UI report bundle to align with backend changes.

Reviewer's Guide

Removes redundant URL encoding when building hardened image PackageURLs, enables the Hummingbird hardened recommendation provider by activating its URL config property, and updates the generated UI report bundle.

File-Level Changes

Change	Details	Files
Stop double-encoding the repository_url qualifier when constructing hardened image PackageURLs.	Replace URLEncoder.encode(path, UTF-8) with the raw path value when assigning the repository_url qualifier. Rely on the PackageURL constructor to handle encoding of qualifier values instead of pre-encoding.	src/main/java/io/github/guacsec/trustifyda/integration/providers/trustify/hardened/HardenedImageResponseHandler.java
Enable the Hummingbird hardened recommendation provider via configuration.	Uncomment and activate the trustedcontent.recommendation.hardened.url property wired to HUMMINGBIRD_URL. Keep existing refresh interval and lock TTL configuration for the hardened provider.	src/main/resources/application.properties
Update the generated UI report bundle.	Regenerate or update the main.js bundle for the UI reports template.	src/main/resources/freemarker/templates/generated/main.js

Hey - I've left some high level feedback:

• In containerRefToPackageRef, consider adding a brief comment explaining why repoUrl is left unencoded to avoid future double-encoding regressions when working with PackageURL.
• Uncommenting trustedcontent.recommendation.hardened.url means the provider may now initialize even when HUMMINGBIRD_URL is empty; it may be worth adding a guard or validation to avoid starting the hardened provider without a valid URL.
