Stop trusting the roots behind the compromised eMudhra intermediates - #179
Merged

Conversation
Debian's ca-certificates 20250419+deb13u1 drops emSign ECC Root CA - G3 and Comodo AAA Services root, which the compromised eMudhra intermediates (and their Sectigo cross-signs) chain to. Images built before that update still trust them. Rebuild both images and fail the build if either root is still in the system trust store. Bump COLLECTOR_VERSION to 1.1.51.

The private keys of eight eMudhra intermediate CAs are recoverable (details). They chain to emSign ECC Root CA - G3 and, through Sectigo cross-signs, to Comodo AAA Services root.

The Vector 0.47.0 binary embeds its own Mozilla root list (rustls / webpki-roots), which still includes both roots. Vector's main HTTP sinks use OpenSSL and the system store, so this PR fixes them. Components that use the embedded list are not fixed; the likeliest is the MongoDB driver. Closing that needs a Vector upgrade or an explicit CA file on those components, tracked separately.
