Use word-boundary matching for personnel name blocklist

Devin Review correctly flagged that the bare "NO" and "KET" entries
in the blocklist would silently drop common Indonesian names (KETUT,
NOVA, NOOR, NORMAN, NOVIANTI, ...) because the check used startswith
rather than a word boundary.

Replaced the per-prefix loop with a single compiled regex anchored at
^ with a trailing \b, which still matches column headers like "NO"
or "KET" on their own line but no longer rejects "NOOR HIDAYAT" or
"KETUT WARDANA". Also fixes the same bug in _following_jabatan.

Added two regression tests covering both directions: names starting
with the offending tokens are kept, bare column headers still rejected.
