fix(ticketrecurrents): remove is_recursive to hide child entities checkbox

• I have performed a self-review of my code.
• I have added tests that prove my fix is effective or that my feature works.
• This change requires a documentation update.

Description

• It fixes !36797
• This PR removes the is_recursive field from the glpi_ticketrecurrents table, because the concept of recursivity was not necessary and led to confusion. This might suggest that recurring tickets were also created in all child entities. Since this field has no impact on them, it was not relevant to display it.

Screenshots (if appropriate):

note that with is_recursive it was possible to ‘see’ the configuration of a recurring ticket in the sub-entity but without being able to update them (logical)

@stonebuzz set milestone to 10.0.19; but PR targets main.

If that's a bug (sounds like it is), it should target 10.0/bf branch.

I don't fully understand the confusion, but I also can't say there isn't a use for having this flag here.

Even if it is a bug, I don't think it is a good idea to target 10.0. There are too many unknowns IMO and removing a feature that has existed over a decade and affects visibility seems far too dangerous.

Sorry it's for main
