Backend serializes SQLite-read (naive) UTC datetimes without a Z, so the browser was parsing them as local time -> the UI effectively showed UTC values. - New src/utils/datetime.ts: treats a tz-less timestamp as UTC, then formats in the browser's local timezone with hour12:false (no AM/PM). - Applied to Energy tabs (contracts/prices/costs/DSMR), per-device readings & trends, and the meter readings table on the Records page. - CostView Today/This month now use local day boundaries (queries stay UTC ISO). - Untouched: location/poo (raw Zulu strings), the map, and query-window params. - Tests are timezone-independent (verified under TZ=America/Los_Angeles).

/**
|
|
* CostView — cost trends + detail + summary.
|
|
*
|
|
* Features:
|
|
* - Date range selector: Today / This month / Custom (SegmentedControl + DateInput).
|
|
* - Recharts AreaChart showing import_cost, export_revenue, net_cost per period.
|
|
* - Table showing per-15min periods with time, kWh values, costs, degraded badge.
|
|
* - Summary cards: metered import/export, fixed costs, credits, total payable.
|
|
* - "Recompute" button with confirmation.
|
|
* - Loading/error/empty states, degraded period highlighting.
|
|
*
|
|
* Recharts imports are isolated to this file only.
