feat: persistent hidden categories with wizard and toggle

Categories to hide are stored on woo.instance and persist across sessions.
Click 'Hidden (N)' button to open wizard where you can add/remove categories
using a tag picker. Eye/eye-slash toggle to quickly apply or unapply the
filter without losing the saved list.
