- Extract _buildWaveformCharts() shared renderer used by both live Events
tab and new DB history modal (no duplicate chart-building code)
- Replace window.open(waveform_viewer.html) with openDbWaveformModal()
that renders an inline overlay with full peaks bar, debug panel, and
4-channel charts — same rendering path as the live device view
- Fix timestamp display for DB blobs (ISO string vs {display:...} object)
- Normalize old blob peak_values keys (tran/vert/long → tran_in_s etc.)
for backward compat with pre-fix ACH blobs
- Close modal via × button, Esc key, or backdrop click; destroy Chart.js
instances on close to free canvas memory
- Fix onclick UUID quoting in History table (UUIDs need quoted string arg)
- Fix ach_server.py peak_values key names to match viewer expectations
- Extract _fillDebugPanel() so same debug content works in both contexts
