Fix nginx: use rewrite+internal location instead of proxy_pass inside if/regex

Browse Source 
proxy_pass with URI component is forbidden inside if blocks and regex locations.
Use rewrite ^ /__clash_api?sub_id=$clash_sub_id last; inside if (safe),
then proxy_pass with URI lives in location = /__clash_api (exact match, internal).
