assets: fix edge-label white-line rendering artifact in remaining 7 diagrams

Same fix as orchestration-flow-patterns.svg (8772564), applied after a
comprehensive re-check that found the bug wasn't limited to the 6 files
originally caught by a narrower pattern match - architecture-overview.svg
and firewall-and-network-docker-bypass.svg were also affected.

Confirmed via a control test on orchestration-flow-patterns.svg that the
.drawio source's labelBackgroundColor property was never the actual
cause (reverted it, re-exported, still broken, still fixed cleanly by
the same strip) - this is a draw.io export-time quirk, not a content or
convention problem, so no CLAUDE.md changes needed.

Each file: stripped the same broken wrapper-div background-color
declarations (flat #1C1D1E / #ffffff, or the equivalent light-dark()/
var(--ge-adaptive-bg) variants - not consistent across exports of the
same file), verified 0 remain, valid XML, and the correct adaptive span
background count unchanged before/after in every file.

Files: architecture-overview.svg, firewall-and-network-docker-bypass.svg,
iac-pipeline-tools-flow.svg, observability-pipeline.svg,
readme-trust-boundaries-blast-radius.svg, secret-distribution-flows.svg,
secrets-and-pki-lifecycle.svg
