refactor(media)!: delete media demo feature

Veect retrofit (ADR-027): third slice of the demo-content removal.
Deletes packages/media whole and prunes every composition edge in one
commit: core-api router mount + dep, core-cms collection composition +
dep + regenerated Payload types, web-next bindAll (prod + dev-seed) +
tests + Tailwind source + transpilePackages + dep, cms/core-cms/web-next
payload config test assertions, tsconfig paths, anchor-guard + generator
e2e feature lists, compliance data-map + retention-policy regeneration,
lockfile prune, and feature-list doc entries (CLAUDE.md, AGENTS.md,
glossary, app/feature AGENTS.md).

Media was the uploads feature: the marketing-pages pages.hero.image and
navigation header.logo upload fields (relationTo: "media") are removed
from those collections in this slice — Payload config sanitization
rejects a relationship to a missing collection. Both features' domain
entities keep their optional imageId/logoId fields; their repositories
already tolerate the fields being absent. Both features are deleted in
later slices.
