fix: add missing shopify.web.toml — root cause of dev preview never loading

shopify.web.toml never existed at the repo root. Without it, `shopify app
dev` runs the theme/UI-extension/Function dev servers fine but never
starts the actual Remix app, and has no local dev-server port to build a
tunnel URL from for the embedded admin app — so Admin always showed the
generic "Find this app in the pages where you work" fallback, regardless
of which app record was linked, cache state, or CLI version. Root-caused
via `shopify app dev --verbose`, which showed the CLI's own reverse proxy
had a route for /extensions but none for /.

Also updates shopify.app.toml's client_id to a freshly linked app (the
previous one, and two accidental duplicates created while chasing this
bug via `dev --reset`/`config link`, were deleted from the Dev Dashboard),
resets application_url/redirect_urls to placeholders now that dev's
auto-update actually works, restores checkout-datetime's network_access
capability (briefly disabled to test an unrelated theory — confirmed not
the real cause), and widens the dev-log gitignore pattern.
