ESP: render damage tags as small left-side labels

Draw ARM/VULN/IMM on the left edge of the box with a 10px font and a black
1px shadow, instead of full-size text above the name. The small font is a
second HFont created next to the 16px body font.

CONTEXT: document the DrawModel argument fix and the tag styling.

   `SetColorModulation(1,1,1)` *before* `DrawModel`.
   Do not force `SetAlphaModulation` there: the earlier attempt produced
   error-material props and a material-system crash.
+- `DrawModel` takes seven arguments after `this`: results, info, boneToWorld,
+  flexWeights, flexDelayedWeights, `const Vector &modelOrigin` (arrives as a
+  pointer) and `flags`. The hook must forward all of them; omitting
+  `modelOrigin` shifts `flags` into its slot and leaves the real `flags` as
+  caller stack garbage, which corrupted roughly every other prop draw
+  (checkerboard / error-material props). Verified against `studiorender.so`
+  0x83ad0: the callee reads `0x20(%ebp)` (modelOrigin) and `0x24(%ebp)`
+  (flags). `DrawModelStaticProp` takes info/modelToWorld/flags only.
 - `prop_tint_update()` also writes `m_clrRender` on prop entities (dynamic
   props) as a secondary path; the netvar resolver rejects offset 0 (an
   embedded-table false positive) and only accepts 0x20..0x2000.
