gauge-complete P4g: MessageBoard reconstructed + registered -> LAST parse-skip cleared (0 unregistered gauges)

Browse Source 
The "messageBoard" cockpit primitive (the secondary-MFD comm/status message ticker,
L4GAUGE.CFG:4913) was PROSE-ONLY (no bodies/methodDescription) -> parse-skipped. This
was the last unregistered gauge primitive.

Reconstructed byte-verified (Make @4cb678, ctor @4cb704, dtor @4cb788, BecameActive
@4cb7fc, Execute @4cb82c; vtable 0051bddc; sizeof 0xA4). THREE header mislabels fixed
(decode + adversarial verify): int enabled -> Entity* trackedMech (a pointer deref'd at
+0x190, set by SetSource not SetEnable); previousMessageId/previousNameId were SWAPPED
(BecameActive writes 0x9c=-1/0xa0=-2; Execute compares messageId vs 0xa0, name vs 0x9c).
Execute blits the strip cell (id -> (id&3)<<7,(id>>2)<<5) + sender name; methodDescription
= 4 params (rate, mode, btsmsgs.pcx, color). Registered in BTL4MethodDescription[].

DEFERRED / EMPTY by design (authentic for bring-up): the source is never bound (SetSource
has no recovered caller) AND the per-player status queue (StatusMessagePool, btstubs.cpp:62)
is a NULL stub -> no status messages exist -> Execute early-returns on the NULL source (safe
no-op == empty board). Data read via a BTResolveMessageBoard bridge in btplayer.cpp (a real
/FORCE-safe stub returning False; the raw mech+0x190/+0x1dc reads stay in the complete-BTPlayer
TU, dodging the databinding trap). The name-cell path is a marked structural simplification to
restore when the feed lands.

VERIFIED: the gauge parse-skip list is now EMPTY ([gskip]=0 -- every config gauge primitive
registered + built); BTResolveMessageBoard resolves (no /FORCE __ImageBase AV); combat TARGET
DESTROYED, no crash; gauge composite renders identically (300/77, clusters, radar un-regressed).
