- Cross-report comparison: toggle panel to load fights from a second
report code, select a fight to use as reference (mutually exclusive
with same-report ref dropdown)
- Fix ref-row player filter: use hiddenPlayerNames (name-based) so
ext-report targets with different actor IDs are correctly hidden
- Fix negative delta formatting: pass Math.abs(diff) to fmtDmg so
negative values are abbreviated the same way as positive ones
