chore(.htaccess): drop no-op QSA flag from RewriteRules

- For Apache `RewriteRule`, if the substitution (right side) has no `?` query part, the original query string is already preserved by default.
- So `QSA` adds nothing in these rules.

Note for the future: QSA will be needed if we ever add a query string on the right (substitution) side. We don't currently so this is just noise in the htaccess rules.
