Better types for brands, tickets, macros, webhooks, articles

[KiraLT]

Pull Request Description

Update types for:

• Brand API types
• Webhooks API types
• Macros API types
• Knowledge API articles and categories partial types
• Ticket API via field, updated getComments type

This PR mostly adds typing using comments. To add Brand type I needed rename Brand client to Brands, but that rename affected only internal import, from external API nothing changed. We can do either that, or change brand type to something else if we wish to avoid this change.
