fix: clear queue endpoint error with redis script

Error message:
```
ReplyError: ERR value is not an integer or out of range script: 720d973b3877f92b4fb3285ced83c97cdd204979, on @user_script:209.
```

The whole error can be tracked back to one of the arguments, which is
`Infinity` in the codebase, but it has to be a number.

The documentation in bullmq says `0` is unlimited[^1], and bullmq tries to
parse the argument with `tonumber` which returns with `-9223372036854775808` if
the argument is `"Infinity"` which is out of bound.

```
127.0.0.1:6379> eval 'return tonumber(ARGV[3])' '2' 'slippy.xyz:queue:inbox:inbox:delayed' 'slippy.xyz:queue:inbox:inbox:events' 'slippy.xyz:queue:inbox:inbox:' '1687183763944' Infinity 'delayed'
(integer) -9223372036854775808
