Migrate AI engine to Claude API; convert stage field to Many2one Kanban model

- Replace fl.case.stage Selection field with Many2one → fl.case.stage model,
  enabling Kanban grouping and dynamic stage management
- Add FlCaseStage model (sequence, fold, description) and fl_stage_data.xml
  with all 11 procedural stages seeded with noupdate=1
- Migrate fl_ai_engine.py from Ollama/llama3.1 to Claude API
  (claude-sonnet-4-20250514); key from ir.config_parameter fl_ai.claude_api_key
- Fix stale field references in _rule_based_tagging and _build_case_context:
  employment/income now read from party_ids, timesharing fields corrected
- Add _fallback_complexity() for graceful degradation when API unavailable
- Add Kanban view to fl_case_views.xml; update action view_mode to kanban,tree,form
- Add fl.case.stage ACL entries to ir.model.access.csv
