SnapOtterandGitHub 32c1192d63 fix(passport-photo): require the face-detection bundle, not just background-removal (#329)
* fix(passport-photo): require the face-detection bundle, not just background-removal

Passport Photo runs face-landmark detection (face_landmarks.py, gated to the
face-detection bundle) before background removal (background-removal bundle),
but it was only declared under and guarded against background-removal. A user
who installed only Background Removal passed every JS-side check, then hit a
late "feature_not_installed" from the Python dispatcher gate when the analyze
step ran face landmarks, and the UI never told them Face Detection was needed.

- shared: add TOOL_EXTRA_BUNDLES + getRequiredBundlesForTool so a tool can
  declare more than one required bundle (passport-photo needs background-removal
  and face-detection). enablesTools is untouched, so the one-tool-per-bundle
  invariant still holds.
- api: isToolInstalled() now checks every required bundle; add
  getFirstMissingBundleForTool() so the analyze and base routes, pipeline (both
  guards) and batch report the bundle the user actually still needs.
- web: the proactive install prompt (tool-page) and features-store treat a tool
  as installed only when all required bundles are present, and point the prompt
  at the first missing one (sequential install, no new UI).

* test(passport-photo): deterministic integration coverage for the two-bundle guard

Boots the real API with an isolated DATA_DIR and controls installed.json to
prove the HTTP route behavior end-to-end:
- nothing installed -> 501 naming background-removal
- only background-removal installed -> 501 naming face-detection (issue #327)
- both installed -> guard passes (not 501)
- base route reports face-detection too
