feat(mocks): retime chart mocks to today; add global/all-slot scripts

Add retimeAnalogInputs.mjs (all slots, single slot, or path)
Add retimeAllCharts.mjs (recursive under chartsData)
Update package.json with npm scripts:
mocks:retime:ai (all analog slots)
mocks:retime:ai:slot (single slot via %SLOT%)
mocks:retime:all (entire chartsData tree)
Preserve relative deltas; set first entry to today (same time); DIA2 daily at 00:00
Skip files/arrays without parsable "t" timestamps
