refactor(app): unify settings tab design for tags, templates & crowd types

Move crowd types management to organisation settings as a new tab and
align all three settings tabs (Tags, Registration Field Templates, Crowd
Types) to the same layout pattern: header with title/subtitle, VDataTable
for active items, and a separate inactive section with VList. Also fix
the API to return inactive records for person tags and registration field
templates so the frontend can display them.
