refactor(mobile): adopt shared interaction semantics

[richardsolomou]

Problem

Mobile still duplicates MCP, skill, permission, composer, session, and inbox presentation behavior after the shared policies have been extracted.

Depends on #3640
Refs #2416

Changes

Phase 2: I migrated mobile onto the shared interaction and presentation policies, then removed the replaced mobile implementations. Shared desktop behavior remains unchanged in this PR.

How did you test this?

• Full monorepo typecheck at this checkpoint
• Final stack: 711 shared, 153 API-client, 2,599 core, and 451 mobile tests
