SeekVoltageGraph: full reconstruction -- the eng-page POWER graph + top-box eraser (Gitea #11)

Browse Source 
The #10 audit's one WRONG: the port Execute was a bring-up no-op, so the
emitter/myomer engineering pages never erased their top data box -> stale
sibling-page ghosts on the shared Eng bit-plane (SYSTEM 10 PPC showing the
Streak ammo box, etc).  Full faithful widget landed:

- btl4gau2: ctor/BecameActive/Execute/clear/ticks/cursor recovered from the
  capstone disasm of @004c6798/@004c6920/@004c6934/@004c6be4/@004c6c30/
  @004c6c6c (Ghidra dropped every x87 arg).  Plot: v=0..12000 step 1200,
  x=Round(response(v)*230), y=Round(v*(1/12000)*187) (ld80 @004c6bd0/@004c6d74
  = exactly 1/12000); change-test samples the response at 12000V vs the 9999
  activation sentinel; XOR op for tick/cursor move-by-redraw; destroyed branch
  centres edestryd.pcc and revives via own vtbl+0xC (BecameActive, slot 3 of
  PTR_0051a1fc -- vtable-dump verified).
- The vtbl+0x3C sampler identified from the binary vtables: Emitter slot 15
  @004bb42c = sqrt(P(v)/2.0e8), P @004bb3f4 = damageFraction*v^2*0.5*
  energyCoefficient; Myomers slot 15 @004b8f94 = sqrt(AvailableOutput(v)*3.6/
  350).  FUN_004dd138 == sqrt (part_015.c:4026): myomers' fabs reading
  corrected, GetSpeedReading renamed SeekVoltageResponse.  Port dispatch via
  complete-type bridges BTSeekVoltageSample/BTMyomersSeekSample +
  BTSubsystemDestroyed (databinding rule).
- Emitter's AUTHENTIC attribute table recovered (binary @0x511dd4, ids
  0x1D-0x25) and published: Laser*/Seek*/OutputVoltage@0x414 (currentLevel,
  RAW volts -- the live-cursor feed).  Field renames per the table:
  0x3F8 minSeekVoltageIndex / 0x3FC maxSeekVoltageIndex (static_assert-locked).
  The MechWeapon 0x1D OutputVoltage PORT ALIAS retired (binary table ends
  0x1C; Find walks lowest-id-first, the alias shadowed the authentic row).
  PPC::DefaultData -> Emitter::GetAttributeIndex().
- mech4: BT_PRESET_HOLD=<n> (freeze the #9 preset cycler after n pulses) for
  steady-state pixel verification; BT_SEEK_LOG diag.

Verified live (BLH, autofire): both #10 repro pairs held ghost-free for
minutes (SYS09->SYS10 PPC, SYS02->SYS04 ERMed, SYS05->SYS06 Myomers); curves
draw with live cursors; one replot per activation; quad panels/J-K-L/sec
panel un-regressed.
