isaac 9205fb2303 Fix inline emoji/image line-height inflation in InstantPage V2 ... The V2 line-breaker used `lineAscent` as both the line height and the baseline offset, then inflated it to each inline emoji/image's full visual size and bottom-aligned the attachment on that inflated baseline. A 24pt emoji on a ~17pt line therefore doubled the line height and shoved the text baseline (and all text on the line) down. Stop inflating the line for emoji/images (only formulas, which carry their own metrics, still grow it) and center each attachment on the font line box at `baselineY - fontLineHeight/2 - size/2`, matching V1 `layoutTextItemWithString` and the chat `InteractiveTextComponent`. The attachment now bleeds symmetrically instead of moving the baseline. `extraDescent` absorbs tall-attachment bottom overflow so the next line is not overlapped, and the streaming-reveal `characterRect` is centered in lockstep so the reveal mask tracks the cell (reveal cost stays width-only).
