merge: resolve conflicts with main branch

DBEditTimeChartForm.tsx was refactored into a directory on main (PR #2026).
Applied our changes (getTraceDurationNumberFormat import, autoDetectedNumberFormat
computation, defaultNumberFormat prop on ChartDisplaySettingsDrawer) to the
new EditTimeChartForm.tsx file. Deleted the old monolithic file.
