fix: add missing proxy support to requestImages() and restore analysis tests

Add addProxyAgent() call to requestImages(), which was the only request
function missing proxy support. Restore and fix all analysis tests that
were excluded from CI via --grep --invert: migrate MSW v1 to v2 API,
fix stale header/option names (ex-provider-1-token → trust-da-token),
add temp file setup for requestStack/requestComponent tests, and add
addProxyAgent unit tests with actual agent verification.

Implements TC-3922
