Import a TradingView chart export as a raw series file, for the backfill (0.3.1) - #32

…ill (0.3.1) A first fill of a series' history is not a 5000-bar pull through the Desktop routine: writing thousands of bars verbatim through a language model is slow, expensive and, with no stored bars for the overlap guard to catch a slip against, unchecked. TradingView's own "Export chart data" CSV is exact and needs no transcription, so `--tradingview-csv PATH --symbols SYM` converts one export into a raw file in the connector's shape (`<date>-csv-export.json`, carrying "source": "csv-export"), and the ordinary `--build-tradingview` then applies every guard it has, the registry anchors included. Exports arrive with `time` as unix seconds or an ISO timestamp, in either order; both are handled, and the ISO path converts through Timedelta arithmetic because pandas may parse at microsecond resolution and an integer cast would silently change unit (the first test run caught exactly that).
