refactor: consolidate IPC bridge to native-only

Remove business IPC handlers/preload APIs that are now served by
Internal HTTP Server: preferences, NLP, data queries, message search,
analytics, members, SQL lab. Migrate chart modules from window.*Api
direct calls to useDataService() and NLP components to HTTP.

Make Internal Server a hard dependency, delete ElectronDataAdapter/
MessageAdapter/PreferencesAdapter and IPC fallback path. Retain IPC
only for native capabilities: file import, AI/LLM, session-index
summaries, agent streaming.
