Subject: Add option to apply filter actions to existing articles (#7959)

* Add option to apply filter actions to existing articles

* make fix-all

* Fixes

* Another approach with preview

Additional improvements:
* Also implemented at category level, and at global level
* Also implemented for favourites at global level

Shortcomings:
* Does not always work reliably with advanced regex, since the DB's flavour is not necessarily the same than PHP's

Related: https://github.com/FreshRSS/FreshRSS/pull/8141

* make fix-all
