feat(portfolio): extend instrument logo rendering to bonds

- Rename presentation prop stock→wide; BOND section passes wide alongside STOCK
- Add bond test cases: CDN logo, fallback, signed return, single-column grid
- Add other-type regression test (no logo, labeled return preserved)
- Update bundle baseline (+4 bytes)
