feat(eliminate-frontend-makefile): task 3.2 - fix deploy-ha.sh/run.sh messages

Rewords deploy-ha.sh's block comment and two fallback echo lines, and
run.sh's XCE-not-found error, to stop naming the now-deleted
Makefile's build-server/build-cli targets, pointing at /xce-build
apiserver instead. Discovery/control-flow logic in both files is
unchanged (verified line-by-line: no if/elif/else lines touched);
run.sh's XCE default placeholder is untouched by design.

+- [x] 3.2 (P) Update deploy-ha.sh's and run.sh's stale message strings
   - `deploy-ha.sh`: update its `/tmp/apiserver`-fallback branch's two log lines and the preceding block comment describing "two ways" to build apiserver, dropping the `make build-server` mention; its meson-first/`/tmp/apiserver`-fallback discovery logic itself is unchanged
   - `tests/regression/run.sh`: update the `XCE` binary-not-found error to name `/xce-build apiserver` instead of reproducing the deleted `build-cli` target's manual `go build` recipe; its `XCE="${XCE:-/tmp/xce_static}"` default is left as-is (an inert placeholder — callers are still expected to pass `XCE=` explicitly)
   - Observable: neither file's live text names a `make` target anywhere; deleting `src/frontend/Makefile` and re-running each script's own failure path shows only Meson-based guidance
