Tasks

1. Make object URLs origin-relative

• 1.1 In backend/internal/storage/signer.go, return a path-only URL (/api/objects/<key>?e&s) and drop the baseURL field/parameter from Signer/NewSigner; verify with go test ./internal/storage/....
• 1.2 In backend/internal/storage/storage.go, stop passing cfg.Server.BaseURL to NewSigner; verify with go build ./....

2. Remove the base-URL configuration

• 2.1 Remove Server.BaseURL from backend/internal/config/config.go and delete the APP_BASE_URL line from .env.example and the README table; verify go build ./... and that no APP_BASE_URL/Server.BaseURL references remain.
• 2.2 Update every other storage.NewSigner(...) call site (tests/helpers in internal/storage, internal/photos, internal/app, internal/e2e) to drop the base argument; verify with make test.

3. Integration verification

• 3.1 Run make test (backend) and npm run build (frontend); verify both pass and that an issued object URL has no scheme or host.

Workflow follow-up

• Run /opsx-apply to implement this change.
• Archive the change after review and verification (sync the delta spec into storage-backends).
