feat: add 5 trust-comparison query functions for Phase 10.6

Browse Source 
New per-trust-within-directorate queries:
- get_trust_market_share: drugs by trust within a directorate
- get_trust_cost_waterfall: cost per patient by trust
- get_trust_dosing: drug dosing intervals by trust
- get_trust_heatmap: trust x drug matrix for one directorate
- get_trust_durations: drug durations by trust

Also verified existing get_pathway_costs(directory=X) works for
directorate-scoped Cost Effectiveness (no new function needed).

Thin wrappers added in dash_app/data/queries.py.

### 10.6 Trust Comparison query functions
- [ ] Add new/modified query functions to `src/data_processing/pathway_queries.py` for per-trust-within-directorate perspective:
- [x] Add new/modified query functions to `src/data_processing/pathway_queries.py` for per-trust-within-directorate perspective:
- `get_trust_market_share(db_path, filter_id, chart_type, directory)` — drugs by trust within a single directorate (stacked bars per trust instead of per directorate)
- `get_trust_cost_waterfall(db_path, filter_id, chart_type, directory)` — one bar per trust showing cost_pp within that directorate
- `get_trust_dosing(db_path, filter_id, chart_type, directory)` — drug dosing intervals broken down by trust within a directorate
- `get_trust_heatmap(db_path, filter_id, chart_type, directory)` — trust × drug matrix for one directorate (rows=trusts, cols=drugs)
- `get_trust_durations(db_path, filter_id, chart_type, directory)` — drug durations by trust within a directorate
- `get_directorate_pathway_costs(db_path, filter_id, chart_type, directory)` — pathway costs filtered to one directorate (same as existing `get_pathway_costs` with directory param, but verify it works correctly)
- [ ] Add thin wrappers in `dash_app/data/queries.py`
- [ ] Verify all queries return correct data for both "directory" and "indication" chart types
- `get_directorate_pathway_costs(db_path, filter_id, chart_type, directory)` — verified existing `get_pathway_costs(directory=X)` works correctly (no new function needed)
- [x] Add thin wrappers in `dash_app/data/queries.py`
- [x] Verify all queries return correct data for both "directory" and "indication" chart types
- **Checkpoint**: All 6 query functions return correct per-trust data for sample directorates
