refactor(V2): alpaca client da alpaca-py a httpx puro (parità V1)
Riscrive `AlpacaClient` su `httpx.AsyncClient` rimuovendo ogni dipendenza runtime da `alpaca-py`. 4 endpoint base distinti (trading paper/live, stock data, crypto data, options data) gestiti via helper `_request` con header `APCA-API-KEY-ID` / `APCA-API-SECRET-KEY`. Firma costruttore e attributi pubblici (`paper`, `base_url`) invariati; `base_url` override applica al solo trading endpoint. Nuovo `aclose()` per cleanup connessioni. Test riscritti su `pytest-httpx` (29 test alpaca + leverage cap). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

"""Alpaca client su httpx puro (V2.0.0).
|
||||
|
||||
Riscrittura full-REST del client `alpaca-py` originale: 4 endpoint base
|
||||
(trading, stock data, crypto data, options data), auth via header
|
||||
APCA-API-KEY-ID / APCA-API-SECRET-KEY, parità completa con la versione V1
|
||||
(stesse firme, stessa shape dei dict ritornati).
|
||||
|
||||
- `base_url` parametro override applica SOLO al trading endpoint
|
||||
(coerente con `url_override` di alpaca-py.TradingClient). Gli endpoint
|
||||
data restano hardcoded su `https://data.alpaca.markets`.
|
||||
- I metodi ritornano `dict` / `list[dict]` direttamente dal JSON REST
|
||||
(al posto dei modelli pydantic alpaca-py serializzati). Le chiavi sono
|
||||
quelle restituite dall'API Alpaca; equivalgono al `model_dump()` dei
|
||||
modelli SDK precedenti.
