tower 0.61.22 — import filestore-rename: head -1 + debug echo

The grep -oE for instanceCode matches BOTH provenance.instanceCode
AND the v2 root mirror, returning two lines. sed processes each line
but the resulting SOURCE_CODE shell variable was multi-line, which
made the directory check fail (-d "/var/lib/odoo/filestore/odoo16
[newline]odoo16") → rename branch silently skipped → Odoo with
db_name=odoo16v2 looks at /var/lib/odoo/filestore/odoo16v2/, finds
nothing, returns 500 on every asset.

Added head -1 to the pipe so SOURCE_CODE is single-line, plus an
echo so the rename branch's path is visible in Job logs even when
it short-circuits.
