Score replication: peers' scores now reach every pod (rank fix)

Field report (playtest night, voice channel): everyone's HUD showed
them in 1st place.  Root cause: the engine's score-replication
machinery was complete -- Player::WriteUpdateRecord ships currentScore,
the replicant ReadUpdateRecord applies it, CalcRanking sums every
scoring player -- but nothing marked the player's update record dirty
on a score change (the engine only ForceUpdates at mission end for the
fade sync).  Every peer's replicant player therefore stayed at score 0
and each machine ranked its own (only-nonzero) player first.

Fix: ForceUpdate() after every score application in the BTPlayer
handlers (main, inflicted, and the severed-vehicle branch) -- the
existing update-record path does the rest.

Verified 2-node (force-damage kill scoring): the victim's machine ranks
the killer's REPLICANT at its replicated score (24) above its own
master (0); standings consistent on both nodes.  BT_RANK_LOG=1 kept as
the 1 Hz per-player ranking dump.
