fix(components): Divider accessibility defaults can't be overridden (#224)

## Summary
- `Divider.tsx` spread `{...rest}` after its `accessible={false}` /
`importantForAccessibility="no"` defaults, so a caller passing either
prop explicitly could override Divider's "hidden from assistive
technology" behavior.
- Reordered so the component's own defaults always win, since Divider is
purely decorative and no legitimate use case was found for making it
independently accessible/focusable — same reasoning as the `disabled`
merge fix in #221 for Button/IconButton/Input/TextArea.
- Added a regression test asserting
`accessible`/`importantForAccessibility` can't be overridden via props.

Fixes #219

## Test plan
- [x] `pnpm jest Divider` — 4/4 pass
- [x] `pnpm lint` — clean
- [x] `pnpm check-types` — clean
- [x] `pnpm prettier --check` — clean
