Camera-seat ranking window LIVE: the 1995 broadcast overlay reimplemented

Browse Source 
The stubbed dpl-instance ranking display is reborn as screen-space
quads in CameraShipHUDRenderable::Render:
  - followed-player callsign banner (bottom center; the old direct
    index was correct -- Execute already converts to the 0-based
    texture slot)
  - the RANKING WINDOW: one row per scoring player, [ordinal][callsign]
    in rank order right of center; visibility = the Director's
    authentic flash logic (10s on / 15s off, solid final 30s); rows
    follow LIVE playerRank pointers so they re-sort as scores change
  - discovery: each 128x32 ordinal bitmap packs TWO ordinals side by
    side ('1st|2nd', '3rd|4th' -- why 4 bitmaps serve 8 players);
    draw = texture rank/2 with a u-half selected by rank parity
  - alpha-blended A4R4G4B4 white-on-transparent textures x green
    diffuse = the authentic green look

BT_SHOT moved AFTER the 2D pass -- it captured the backbuffer pre-HUD,
so overlays were on screen but invisible to screenshots (cost one
false debugging round).  GetOrdinalTexture accessor added.

Screenshot-verified: '1st MAVERICK' standings + MAVERICK banner over
live auto-directed coverage; 2-node mech smoke PASS (un-regressed;
the new render path only executes when a CameraDirector HUD exists).
