detected_id (map_vision.read_marker_id) was wired into ground-truth
logging but never actually consumed when accepting a proposal --
every accepted target/ally silently got an auto-assigned A/B/C letter
regardless of what number the game itself shows for that unit.
_accept_proposal now prefers detected_id when present, falling back to
auto-assign on a collision (two markers misread to the same id, or a
real id that happens to match one already assigned) -- a duplicate id
is worse than losing traceability to the game's own number for that
one accept. Targets/allies keep their own separate id namespace, same
as auto-assignment already does elsewhere.
