fix(api): use global undici dispatcher for HTTP_PROXY across all data providers

Switch to setGlobalDispatcher(new EnvHttpProxyAgent()) at bootstrap so every
service that uses native fetch picks up HTTP_PROXY / HTTPS_PROXY / NO_PROXY
without per-call wiring.

Reverts the inline ProxyAgent in manual.service.ts because the global
dispatcher covers it (and the other 7 services that hit native fetch:
coingecko, openfigi, trackinsight, eod-historical-data,
financial-modeling-prep, ghostfolio, rapid-api). Also gets NO_PROXY
handling for free, which the inline ProxyAgent path did not have.

Matches the approach @dtslvr suggested in #6206.
