[Feature request] Improve global filter with regex and use multiple times the same type of filter

[Mushr0000m]

Describe the feature or enhancement

Hi, Umami is really great but I think it lack flexibility for global filters :

1. Having the possibility to use only one type of filter is problematic, right now if I use a filter for "path" I can't have an other path filter. For example filter path containing en/shop OR fr/boutique, it's the same for other types of filters. Same goes for segments.
2. In the same area, the 'contains' filter is good but a regex would be better or a wildcard. In our case we need to filter users that visited en/shop/*/reviews. It happens multiple times that we need to create more complex pattern search than just exact match or contains.

We will be introducing or logic in the next release. Users should be able to to do multiple and/or blocks if the same filter. The regex wildcard is interesting. I need to see what functions are available in clickhouse and postgres.
