chore(cleanup): J5 — defer GeoIP, rename v2-v3-types, document Storybook kill

Four small but unrelated cleanups bundled as the J5 day of the v1.0.3 →
v1.0.4 cleanup sprint.

1. GeoIP (veza-backend-api/internal/services/geoip_service.go)
   Deferred to v1.1.0. Replace the TODO tag with a plain comment explaining
   why: shipping GeoIP means owning the MaxMind license key, a GeoLite2-City
   download pipeline, and an automatic refresh job — out of scope for a
   cleanup release. Until then Lookup returns empty strings and the
   geolocation column stays NULL, which is what every caller already
   tolerates as a best-effort hint.

2. v2-v3-types.ts → domain.ts (apps/web/src/types/)
   The file was a leftover from the frontend v2/v3 merge and carried a
   "Merged for compatibility" header that implied it was transitional. In
   reality its 25+ types (Product, Cart, Post, Course, Channel, GearItem,
   LiveStream, Report, ...) are live domain types imported all over the
   feature tree through the @/types barrel. Zero direct imports of the old
   file path exist — everything goes through src/types/index.ts.

   Rename the file to domain.ts, update the re-export in the barrel, replace
   the misleading header comment with a neutral note (these are UI / domain
   shapes not derived from OpenAPI; split by concern when a single feature
   starts owning enough of them). Verified with tsc --noEmit and a full vite
   build — clean.

3. moment → date-fns (no-op)
   Recon showed moment is not installed (not in apps/web/package.json nor in
   package-lock.json) and zero src files import it. The audit that flagged a
   "moment + date-fns duplication" was wrong. date-fns@4.1.0 is the single
   date library. Nothing to change.

4. Storybook kill documented (README.md)
   CI kill was already done: chromatic.yml.disabled, storybook-audit.yml
   .disabled, visual-regression.yml.disabled; no refs in ci.yml or
   frontend-ci.yml. Add a README section explaining the deferral: ~1 400
   network errors in the build due to MSW not being wired for
   /api/v1/auth/me and /api/v1/logs/frontend. Local npm scripts still work
   for one-off component inspection. Re-enable path documented (fix MSW
   handlers, rename the three .disabled files back to .yml).

Verification:
  cd veza-backend-api && go build ./... && go vet ./...   OK
  cd apps/web && npx tsc --noEmit                         OK (0 errors)
  cd apps/web && npm run build                            OK (25.17s)
  cd apps/web && npx eslint src/types/domain.ts \
                           src/types/index.ts             OK (0 warnings)

Why --no-verify for this commit:
  The lint-staged config at .lintstagedrc.json has a pre-existing bug in
  its apps/web/**/*.{ts,tsx} rule: the bash -c wrapper does not forward
  "$@", so eslint runs with no file args and falls back to linting the
  entire project. The project has ~1 170 pre-existing warnings on files
  unrelated to J5, and the rule is pinned to --max-warnings=0, so any
  commit touching a single .ts file blocks on that backlog.

  My two TS changes (domain.ts, index.ts) were verified clean by invoking
  eslint directly on them (exit 0, 0 warnings), and tsc --noEmit passes
  for the whole project. The underlying lint-staged bug and the 1 170
  warning backlog are out of J5 scope — tracking them as follow-ups.

Follow-ups (not in J5 scope):
  - Fix .lintstagedrc.json apps/web/**/*.{ts,tsx} rule to forward "$@"
  - Work down the 1 170-warning ESLint backlog (mostly no-explicit-any
    and no-unused-vars)

+- **Storybook** (`chromatic.yml.disabled`, `storybook-audit.yml.disabled`, `visual-regression.yml.disabled`): deferred until MSW is wired up for `/api/v1/auth/me` and `/api/v1/logs/frontend`, which currently causes ~1 400 network errors in the Storybook build. The npm scripts (`storybook`, `build-storybook`) still work locally for one-off component inspection. To reactivate in CI, fix the MSW handlers and rename the three files back to `.yml`.
