chore(lint): apply eslint auto-fixes across the .tsx backlog

Mechanical --fix output over the newly linted .tsx files (indent,
arrow-parens, comma-dangle, member-delimiter-style, unnecessary type
assertions), plus the three generic-arrow test hooks converted to
function declarations up front: the comma-dangle fixer strips the
<T,> disambiguation comma and turns them into parse errors otherwise.
