feat: eco calendar bootstrap + driver types + timeline cursor
Backend:
- eco_calendar_bootstrap.py: 75 historical events 2020-2026 (FOMC, NFP,
CPI, GDP, ISM, BOJ, ECB, BOE) with expected_value/actual_value/
surprise_pct/unit/absorption_pct fields
- database.py: 5 new columns on market_events (expected_value,
actual_value, surprise_pct, unit, sub_type) + updated save_market_event
- timeline.py: POST /api/timeline/bootstrap-eco endpoint
- instrument_service.py: _get_relevant_events now returns eco fields
- instruments.json: type field on all 90 drivers across 20 instruments
(event_calendar | report | geopolitical | fundamental | sentiment | technical)
Frontend (InstrumentDashboard):
- EventTimelineStrip: vertical cursor line tracking crosshair selectedDate
- EventsCard: active-event highlight at hovered date + expected/actual/
surprise_pct display + absorption progress bar
- DriversPanel: type selector dropdown per driver
- DriverTypeBadge: colored micro-badge on driver labels in strip
