fix(db): drop dead quote tracking in hasExecutableSql, clear lint

hasExecutableSql returns as soon as it meets a quote character, so the quote
variable was assigned and never read: the `if (quote)` branch could never run.
eslint reported it as a useless assignment and the error blocks the release
gate on main. Removing the variable and the unreachable branch keeps behaviour
identical, since encountering a quote already means the SQL is executable.

Also drops an eslint-disable directive in csr's output error reporter that
suppressed nothing.
