feat: dead-config sweep, test suite foundation, widget settingsSchema validation

Sprint G: audited every BootstrapConfig field for a real runtime consumer
(docs/DEAD-CONFIG-AUDIT.md). Wired 3 previously-dead editable fields:
footer.logoUrl, company.address.street/contacts.phone, catalog.suggestionsEnabled.
Remaining dead fields needing a business/design decision tracked in
PRODUCT_BACKLOG.md/KNOWN-ISSUES.md, not silently left.

Sprint H: 6 new spec files (test count 57 -> 83), covering ProjectEditorFacade
(undo/redo, draft persistence, publish gating), AdminAnalyticsFacade
(never-fabricate-a-number contract), and regression coverage for this
session's carousel/hero/profile-toggle fixes.

Sprint I: widget settingsSchema (declared in widget-manifest.json, never
validated) now enforced via a new lightweight schema check in
ProjectValidator, surfaced through the existing issuesByField pipeline.
Same check reused in diagnostics so editor and diagnostics can't disagree.

Verification: tsc clean, ng build clean, 83/83 tests pass, barry-cache
validate clean (2 pre-existing unrelated warnings only).
