Mem-Client: MDS Component Names Start With MDS

MDS component naming prefix rule.

Scope:
- Applies to new exported React components under `domains/frontend/mem-client/src/mds/components/**`.
- Ignore `*.stories.tsx`, `*.style.tsx`, `*.types.ts`, and `index.ts`.

Trigger:
- Added exported component identifiers in scope.

Hard requirements:
1) Exported component names must start with `MDS`.

Decision:
- Return NOT APPROVED when trigger is met and a new exported component name does not start with `MDS`.
