.tsx sources and specs were invisible to every lint surface: the eslint
flat-config globs, the lefthook staged-file glob, and the jscpd clone
scan all matched *.ts only. Widen the five eslint file groups (source,
test, client-test, sonar, formatting), the pre-commit glob, and the
jscpd format/pattern to cover .tsx.
Existing .tsx files predate these lanes; follow-up commits on this PR
clear the backlog they surface.
