score/ts_client: Create detailed design (comp_dd_sta)

[lavrovvalera]

Important

Link the implementing PR to this issue by including Closes #89 in the PR description or commit message.

What

Write the detailed design document for score/ts_client.

Create score/ts_client/docs/detailed_design/index.rst using the sphinx-needs comp_dd_sta directive. Decompose the component into units, document their responsibilities and interfaces, and connect every unit to requirements (:implements:) and architecture (:satisfies:).

Note: Create this ticket after PR #54 merges, as it changes the shared memory layer architecture.

Units to cover: GptpIpcPublisher (writes gPTP data into shared memory), GptpIpcReceiver (reads data from shared memory), GptpIpcChannel (shared memory management layer); data format in shared memory.

Acceptance Criteria

• comp_dd_sta directive in place with :status: valid
• Shared memory protocol (data format, publisher/receiver contract) described
• :implements: and :satisfies: links present for every unit
• req-Id traceability comments in source for every traced unit
