refactor: Phase 10 — Ollama service, image cache, config, frontend orphans

Final cleanup phase of the MCP-first pivot.

docker-compose:
  - docker-compose.yml: drop ollama service + OLLAMA_URL/MODEL env vars +
    IMAGE_CACHE / VAPID env comments
  - docker-compose.prod.yml: drop ollama service + Ollama env + GPU
    reservation
  - docker-compose.quickstart.yml: drop ollama service + Ollama env +
    GPU-reservation comment; quickstart instructions now point at the
    MCP Access tab instead of model-pull

Config:
  - Drop OLLAMA_URL, OLLAMA_MODEL, OLLAMA_BACKGROUND_MODEL,
    OLLAMA_KEEP_ALIVE_*, OLLAMA_NUM_CTX, EMBEDDING_MODEL (fastembed
    is hard-coded inside services/embeddings.py)
  - Drop IMAGE_CACHE_DIR, IMAGE_MAX_BYTES (image cache subsystem
    deleted)
  - Drop VAPID_PRIVATE_KEY, VAPID_PUBLIC_KEY, VAPID_CLAIMS_SUB (push
    deleted in phase 8)
  - Drop VOICE_ENABLED, STT_BACKEND, STT_MODEL, TTS_BACKEND (voice
    deleted in phase 8)
  - Drop Config.validate() rules for those keys

Image cache deletion:
  - services/images.py, routes/images.py, models/image_cache.py
  - models/__init__.py: drop ImageCache import
  - app.py: drop images_bp registration
  - alembic/versions/0054_drop_image_cache.py: DROP TABLE image_cache

Frontend client.ts orphan exports stripped:
  - getVoiceStatus, getVoiceList, getVoiceLibrary, installVoice,
    uninstallVoice, transcribeAudio, synthesiseSpeech,
    VoiceStatusResult / VoiceEntry / VoiceLibraryEntry types
  - getJournalConfig, saveJournalConfig, getJournalToday/Day/Days,
    triggerJournalPrep, runJournalCurator, listPendingActions,
    approvePendingAction, rejectPendingAction, listJournalMoments,
    updateJournalMoment, deleteJournalMoment, geocodeAddress
  - JournalConfig / JournalLocation / JournalConversation /
    JournalMessage / JournalDayPayload / JournalMoment /
    CuratorRunResult / PendingCuratorAction types
  - consolidateProfile, clearProfileObservations, listProfileObservations
  - ProfileObservationEntry, learned_summary/observations_* fields on
    UserProfile
  - consolidateTask (cascading update to TaskEditorView)
  - getFableMcpInfo, getNewsItems, GetNewsItemsParams, NewsItem import

TaskEditorView:
  - Drop the auto-summary banner + Re-consolidate button
  - Drop isBodyAutoMaintained gate (editor is always user-controlled now)
  - Drop reconsolidate function + reconsolidating ref

SettingsView:
  - profile ref no longer initialises learned_summary /
    observations_count / observations_updated_at (those fields are
    gone from UserProfile type)

Surviving frontend composables/components flagged for likely future
cleanup but not deleted in this commit (no compile errors, just
unreferenced after Phase 7-8):
  - useAssist, useFloatingAssist, useTagSuggestions, useVad,
    useListenMode, useOnnxPreloader (composables)
  - WorkspaceNoteEditor, WorkspaceTaskPanel, WeatherCard, InlineAssistPanel
    (components)
  - api/client.ts still references /api/notes/assist/* and
    /api/notes/suggest-tags via useAssist + useTagSuggestions — those
    endpoints 404 now but no caller hits them; dead at runtime, harmless.

Compose stack collapses to two services: `app` + `db`. No Ollama, no
voice models, no fable-mcp wheel build. First-boot install reduces to:
  docker compose up -d
  → visit web UI → register → Settings → MCP Access → copy snippet
  → claude mcp add … → done.
