refactor: Phase 8 — backend deletion (chat / voice / push / journal / curator)

Mega-commit. Strips all server-side LLM machinery now that Phase 7 has
removed the corresponding UI surfaces and the MCP HTTP endpoint is the
sole assistant interface.

Deleted (services/):
  chat, generation_buffer, generation_log, generation_task, llm, tools/
  (entire package), stt, tts, voice_config, voice_library, push,
  journal_closeout, journal_pipeline, journal_prep, journal_scheduler,
  journal_search, curator, curator_scheduler, consolidation,
  tag_suggestions, research, weather, article_fetcher, pending_actions,
  moments, assist, wikipedia.

Deleted (routes/):
  chat, voice, push, journal, quick_capture, fable_mcp_dist.

Deleted (models/):
  conversation, generation_tool_log, push_subscription,
  pending_curator_action, moment, weather_cache.

Deleted (tests/):
  test_generation_log, test_journal_*, test_consolidation, test_lookup_tool,
  test_notes_consolidation_trigger, test_record_moment_guards,
  test_research_pipeline, test_tools_*, test_tool_use_fixes,
  test_voice_library, test_weather_service, test_calendar_tool_tz,
  test_wikipedia.

Deleted (top-level):
  fable-mcp/ (legacy standalone stdio package — wheel-build pipeline
  also removed from Dockerfile).

app.py:
  - blueprint registrations for the 6 deleted routes
  - startup hook trimmed: no more Ollama warmup, KV-cache priming,
    journal/curator schedulers, voice model loading
  - shutdown hook simplified
  - httpx import dropped (was for Ollama calls)

pyproject.toml:
  - removed deps: pywebpush, feedparser, html2text, trafilatura
  - removed [voice] extras entirely
  - description updated for the MCP-first architecture

Dockerfile:
  - removed faster-whisper / piper-tts install steps
  - removed bundled piper voice download stage
  - removed fable-mcp wheel build stage

Surviving-file edits:
  - services/auth.py: drop Conversation table claim on first-user setup
  - services/backup.py: drop conversation / push-subscription export+restore;
    v1/v2 restore now silently skip pre-pivot conversation data
  - services/notes.py: drop maybe_consolidate trigger on task done/cancelled;
    drop _maybe_trigger_project_summary (LLM auto-summary)
  - services/projects.py: drop generate_project_summary + backfill_project_summaries
    (both LLM-driven)
  - services/user_profile.py: drop append_observations / consolidate /
    clear_learned_data (curator-tied) and build_profile_context
    (was LLM system-prompt builder)
  - services/notifications.py: stub out _fire_push_notif (was send_push_notification)
  - services/event_scheduler.py: drop event-reminder push + chat-retention
    cleanup job; keep CalDAV pull-sync + reminders job (in-app)
  - services/diagnostics.py: _curator_busy() always False
  - routes/notes.py: drop /assist, /assist/stream, /suggest-tags endpoints
  - routes/tasks.py: drop /<id>/consolidate endpoint
  - routes/settings.py: drop /models, KV-cache-prime-on-save, journal-schedule
    timezone hook, and the SearXNG search-test endpoint; inline _is_private_url
    (was in services/llm.py)
  - routes/admin.py: drop /voice, /voice/reload endpoints
  - routes/profile.py: drop /consolidate, /observations (GET, DELETE)
  - models/__init__.py: drop the 6 dead model imports

Frontend cascade:
  - stores/push.ts: deleted entirely (no callers after Phase 7)
  - stores/settings.ts: drop checkVoiceStatus + voice-status state
  - views/SettingsView.vue: drop Locations section + journalConfig state
    (was tied to /api/journal/config); drop JournalConfig + journal/voice
    api/client imports
  - frontend/api/client.ts: orphaned voice/journal/profile-observation/
    fable-mcp-dist exports are left as dead but harmless (call them and
    they 404; type-check is clean).

Pre-existing v1 backups that contained conversations/messages still
restore — those tables are silently dropped from the import path.
Anyone pulling the new image with a populated database will need the
Phase 9 migration to drop the dead tables (coming next).
