Stats panel: FBR breakpoints, physical pierce, and a side panel with more player stats

[errolgr]

Summary

Adds rows players asked for to the advanced stats panel: physical pierce, an FBR breakpoint line with block frames, dodge/avoid/evade, off-weapon ED and ED vs demons/undead, active auras and oskills with their levels, base (hard-point) vs total attributes, and a +skills summary.

Problem

The panel shows FCR/FHR breakpoints but not FBR. It shows elemental pierce but not physical pierce (PD2 stat 425). It doesn't show several stats that are only visible on item tooltips: Dodge/Avoid/Evade (STAT_DODGE/AVOID/EVADE are defined in Constants.h but never drawn), off-weapon ED, ED vs demons/undead, auras, oskills, +skills, and hard points vs total attributes.

The main panel is already 558 px tall in a 600 px-high game, so it has room for only two more rows.

Changes

File	Change
BH/Drawing/Stats/StatsDisplay.cpp	Main panel: Physical Pierce row after Elemental Pierce; FBR line after FHR (player tab). Panel height +32 (590 px).
	GetBlockBreakpoints: FBR thresholds and current block frames from the block (BL) AnimData record of the current class/form/weapon class. It uses the same ConvertMode + GetAnimDataRecord lookup as the IAS line, frames = ceil(256*F / floor(speed*(50+EFBR)/100)) - 1, with base 100 under Holy Shield. No hard-coded table.
	DrawSidePanel (player tab only): a second box of the same width next to the main one (left of it with statsOnRight). Contents: attributes base/total; all/class skills and each class skill-tab bonus (game text from CharStats StrSkillTab1-3); running own aura and item auras with level; oskills with total level; dodge/avoid/evade; block frames; off-weapon ED; ED vs demons/undead. Clicking it closes the panel, like the main box.
BH/Drawing/Stats/StatsDisplay.h	Declarations, side-panel rectangle for InRange.

• Existing rows are unchanged. The merc tab draws neither the FBR line nor the side panel.
• Off-weapon ED is the player's item_maxdamage_percent as is. In game, a weapon's own ED (ItemStatCost op 13) is applied to the weapon and doesn't show up in the player's stat 17: a 100% ED hand axe leaves it at 0, and 30% ED gloves make it 30.
• Not included: auras cast on the player by other units (party, merc). The client has the aura state, but BH has no client-side value for the level of an aura cast by another unit.

Testing

In game (PD2 Season 13 client, single player, Paladin level 50): gear with known stats (cap and gloves, normal quality), Might on the right button, then Holy Shield cast. Every new row is compared to the stats put on the gear. FBR and block frames are compared to the harness's independent rates oracle, which matches the PD2 wiki/maxroll FBR tables.

	Result
Before (current BH, and shipped PD2 BH)	rows not present
After (this PR)	20/20 checks pass

Row	Expected from	Drawn
Strength	100 hard + 15 cap	Strength: 100 / 115
Skills	cap	All Skills: +1, Class Skills: +1, +2 to Offensive Auras
Own aura	Might 10 + 1 all + 1 class + 2 Offensive Auras	Aura: Might (Level 14)
Item aura	item_aura	Aura: Holy Freeze (Level 5)
Oskill	+2 + 1 all skills	Oskill: Teleport (Level 3)
Physical pierce	gloves	Physical Pierce: 15%
Dodge / Avoid / Evade	gloves	11% / 22% / 33%
Off-weapon ED / vs demons / vs undead	gloves	30% / 40% / 55%
FBR 48, Short Sword + Buckler	oracle	FBR: 13 / 32 / 86 / 600, Block Frames: 3
FBR 48 with Holy Shield	oracle	FBR: 86, Block Frames: 2

Unit tests (native build of StatsDisplay.cpp against a fake engine):

• FBR line and block frames match the oracle for every class × weapon class, Holy Shield, and wereforms (180 lines).
• Unit tests also cover attributes, skills, auras/oskills, pierce/avoid and ED rows.

Runtime: 10/10 + 10/10 cold launches (PD2 and vanilla) with the branch build, no crashes. The other in-game scenarios have the same results as on main.
