feat: observation history tracking and diff UI (#513)
* feat: add source facts token limits to consolidation and recall

- Add two new configurable (per-bank) parameters:
  - consolidation_source_facts_max_tokens: total token budget for source
    facts across all observations in the consolidation prompt (-1 = unlimited)
  - consolidation_source_facts_max_tokens_per_observation: per-observation
    cap so each observation gets a fair share of source facts (-1 = unlimited,
    default 256)
- Both are also exposed as recall API parameters via SourceFactsIncludeOptions
  (max_tokens and max_tokens_per_observation)
- Consolidation now uses resolve_full_config to respect bank-level overrides
- Improve consolidation prompt: temporal metadata (occurred_start=, | Involving:)
  is now clearly separated from observation text, with a concrete example showing
  the expected synthesis style and explicit rules not to copy raw fact lines
- Add tests for recall source facts capping and consolidation config forwarding
- Expose all three new fields in the control plane bank config UI
- Document new env vars in configuration.md
- Regenerate OpenAPI spec and all SDK clients

* fix: reorder observations UI fields and rename Label Groups to Entity Labels

* fix: revert Entities section title (only rename inner label)

* doc: add consolidation source facts and batch size fields to memory-banks docs

* feat: add observation history tracking and UI diff view

- Track observation changes over time in a JSONB history column,
  appending each update's previous state (text, tags, dates, sources)
  instead of overwriting
- Add HINDSIGHT_API_ENABLE_OBSERVATION_HISTORY config flag (default: true)
  to toggle history recording
- Expose history field in get_memory_unit for observations
- Fix observations/[modelId] route that was proxying to wrong endpoint
- Add History tab in observation modal and History section in panel,
  showing word-level and tag diffs between each change (newest first)
- Extract shared ObservationHistoryView component used by both modal and panel
- Add --random-port flag to start.sh to run multiple dev instances
- Scope Next.js distDir by port to prevent lock file collisions between instances
- Restyle consolidation pending badge (rounded-md with border) and add
  inline refresh button; fix loading flicker on data refresh

* feat: dedicated observation history endpoint with source facts diff

- Add GET /memories/{id}/history endpoint returning enriched history with
  resolved source fact texts and is_new flags per change
- Deprecate history field in GET /memories/{id} (always returns empty list)
- Reconstruct cumulative source facts per history entry by working backwards
  from current state, marking newly added facts with is_new
- Replace inline history panel with "View History" button opening modal
- History modal fetches from dedicated endpoint lazily on tab switch
- Timeline view now opens MemoryDetailModal instead of side panel
- History view uses prev/next navigation (left = older, right = newer)
- Fix --random-port: pass dynamic API_PORT as HINDSIGHT_CP_DATAPLANE_API_URL
  to control plane, preserving caller values over .env
