Remove dead Travis CI badges from module READMEs (69 repos)

[silug]

Summary

69 repos still carry a dead Travis CI build badge in their top-level README.md. Travis has not run for SIMP in years, so every one of these renders as a broken or misleading build indicator — on the Forge-facing README that is often the first thing a user sees.

The line is perfectly uniform, with only the repo name interpolated:

[![Build Status](https://travis-ci.org/simp/<repo>.svg)](https://travis-ci.org/simp/<repo>)

Verified identical in pupmod-simp-aide, pupmod-simp-ssh, pupmod-simp-cron, pupmod-simp-simp_authselect, so a scripted sweep is safe.

⚠️ This is a scripted sweep, not a baseline-template change

Unlike #45 and #46, README.md is not a puppetsync-managed file. The managed set under
modules/profile/files/pupmod/ is Gemfile, _github/, _pdkignore, _puppet-lint.rc, and the
_rspec* variants — there is no README template. So this needs puppetsync to drive a
scripted per-repo edit and open PRs, rather than syncing a changed template. Worth being explicit
so nobody goes looking for a template that does not exist.

Two options for the replacement

Option A — just delete the line. Simplest, removes the dead badge, no new moving parts.

Option B — replace with a GitHub Actions badge:

[![PR Tests](https://github.com/simp/<repo>/actions/workflows/pr_tests.yml/badge.svg)](https://github.com/simp/<repo>/actions/workflows/pr_tests.yml)

No repo currently uses this, so it would be new across the board. Option B gives a real signal
but will honestly show red wherever master is failing — which today includes plenty of repos
(see the fleet-wide RPM release breakage). That is arguably the point of a badge, but it is a
visible change, so it deserves a deliberate decision rather than being slipped into a cleanup.

Do NOT touch these three

They matched the search but are vendored or fixture content and must be left alone:

• simp/rubygem-simp-cli → ext/gems/highline/README.md (vendored gem)
• simp/rubygem-simp-rake-helpers → spec/lib/simp/rake/pupmod/fixtures/simpmod/README.md (test fixture)
• simp/simp-adapter → spec/fixtures/test_module_rpms/pupmod-simp-site/README.md (test fixture)

Adjacent README hygiene worth folding in

Two more copy-paste artifacts from the original module template, cheap to fix in the same pass:

• The CII Best Practices badge is hardcoded to project 73 in every module — verified identical
  in aide, ssh, cron, and simp_authselect. It is one project's badge pasted fleet-wide, so it
  is wrong (or at least meaningless) on all but one repo. Decide whether to point it somewhere real
  or drop it.
• 2 repos still carry the template's leftover instruction line
  **FIXME**: Ensure the badges are correct and complete, then remove this line! — one of them is
  pupmod-simp-simp_authselect, which is the entire content of
  Update README.md pupmod-simp-simp_authselect#3.

Closing that per-module issue in favor of this one would make sense once this lands.
